  - An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a     use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.
    (CVE-2022-45919)

  - A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when     plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to     the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED     controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led     structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
    (CVE-2023-1079)

  - A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur     when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading     to a denial of service. (CVE-2023-1380)

  - A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks. (CVE-2023-1637)

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

  - Due to a vulnerability in the io_uring subsystem, it is possible to leak kernel memory information to the     user process. timens_install calls current_is_single_threaded to determine if the current process is     single-threaded, but this call does not consider io_uring's io_worker threads, thus it is possible to     insert a time namespace's vvar page to process's memory space via a page fault. When this time namespace     is destroyed, the vvar page is also freed, but not removed from the process' memory, and a next page     allocated by the kernel will be still available from the user-space process and can leak memory contents     via this (read-only) use-after-free vulnerability. We recommend upgrading past version 5.10.161 or commit     788d0824269bef539fe31a785b1517882eafed93     https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/io_uring (CVE-2023-23586)

  - A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

  - An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability. (CVE-2023-32269)

  - An issue was discovered in the Linux kernel before 6.2.9. A use-after-free was found in bq24190_remove in     drivers/power/supply/bq24190_charger.c. It could allow a local attacker to crash the system due to a race     condition. (CVE-2023-33288)

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to     cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other     impact by inducing a high load. (CVE-2018-20784)

  - A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function     tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It     is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this     vulnerability. (CVE-2022-3566)

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-     after-free, related to dvb_register_device dynamically allocating fops. (CVE-2022-45884)

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_frontend.c has a     race condition that can cause a use-after-free when a device is disconnected. (CVE-2022-45885)

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free. (CVE-2022-45886)

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/usb/ttusb-dec/ttusb_dec.c has a     memory leak because of the lack of a dvb_frontend_detach call. (CVE-2022-45887)

  - An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a     use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.
    (CVE-2022-45919)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race     condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

  - In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON     condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a     type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing     memory corruption. (CVE-2023-1077)

  - In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

  - A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the     way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate     their privileges on the system. (CVE-2023-1118)

  - A use-after-free flaw was found in the Linux kernel's core dump subsystem. This flaw allows a local user     to crash the system. Only if patch 390031c94211 (coredump: Use the vma snapshot in fill_files_note) not     applied yet, then kernel could be affected. (CVE-2023-1249)

  - A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur     when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading     to a denial of service. (CVE-2023-1380)

  - A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while     loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system     to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

  - A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some     uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an     information leak. (CVE-2023-1513)

  - A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This     flaw allows an attacker to crash the system and possibly cause a kernel information lea (CVE-2023-1611)

  - A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local     user could use this flaw to crash the system or potentially escalate their privileges on the system.
    (CVE-2023-1670)

  - A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In     this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on     hdev devices. (CVE-2023-1989)

  - A use-after-free flaw was found in ndlc_remove in drivers/nfc/st-nci/ndlc.c in the Linux Kernel. This flaw     could allow an attacker to crash the system due to a race problem. (CVE-2023-1990)

  - The Linux kernel allows userspace processes to enable mitigations by calling prctl with     PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed     that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to     attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be     observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened     because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that     STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection.
    However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons,     which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target     injection against which STIBP protects. (CVE-2023-1998)

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
    (CVE-2023-2162)

  - An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

  - A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free     (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free     that may lead to privilege escalation. (CVE-2023-28464)

  - An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer     overflow. (CVE-2023-28772)

  - The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/power/supply/da9150-charger.c if a physically proximate attacker unplugs a device.
    (CVE-2023-30772)

  - A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in     the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend     upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

  - A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - A use after free issue was discovered in driver/firewire in outbound_phy_packet_callback in the Linux     Kernel. In this flaw a local attacker with special privilege may cause a use after free problem when     queue_event() fails. (CVE-2023-3159)

  - A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and     font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds     occurs leading to undefined behavior and possible denial of service. (CVE-2023-3161)

  - An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability. (CVE-2023-32269)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c. (CVE-2023-35824)

    It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel     contained a type confusion vulnerability in some situations. An attacker could use this to cause a denial     of service (system crash). (CVE-2023-1078)

    Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel did not properly initialize     some data structures. A local attacker could use this to expose sensitive information (kernel memory).
    (CVE-2023-1513)

    It was discovered that a use-after-free vulnerability existed in the iSCSI TCP implementation in the Linux     kernel. A local attacker could possibly use this to cause a denial of service (system crash).
    (CVE-2023-2162)

    It was discovered that the NET/ROM protocol implementation in the Linux kernel contained a race condition     in some situations, leading to a use- after-free vulnerability. A local attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32269)

    Duoming Zhou discovered that a race condition existed in the infrared receiver/transceiver driver in the     Linux kernel, leading to a use-after- free vulnerability. A privileged attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1118)
