The version of kernel installed on the remote host is prior to 5.4.129-62.227. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-004 advisory.

    A flaw was found in the Linux kernels implementation of wifi fragmentation handling. An attacker with the     ability to transmit within the wireless transmission range of an access point can abuse a flaw where     previous contents of wifi fragments can be unintentionally transmitted to another device. (CVE-2020-24586)

    A flaw was found in the Linux kernel's WiFi implementation. An attacker within the wireless range can     abuse a logic flaw in the WiFi implementation by reassembling packets from multiple fragments under     different keys, treating them as valid. This flaw allows an attacker to send a fragment under an incorrect     key, treating them as a valid fragment under the new key. The highest threat from this vulnerability is to     confidentiality. (CVE-2020-24587)

    A flaw was found in the Linux kernels wifi implementation. An attacker within wireless broadcast range can     inject custom data into the wireless communication circumventing checks on the data.  This can cause the     frame to pass checks and be considered a valid frame of a different type. (CVE-2020-24588)

    Frames used for authentication and key management between the AP and connected clients.  Some clients may     take these redirected frames masquerading as control mechanisms from the AP. (CVE-2020-26139)

    A vulnerability was found in Linux kernel's WiFi implementation.  An attacker within wireless range can     inject a control packet fragment where the kernel does not verify the Message Integrity Check     (authenticity) of fragmented TKIP frames. (CVE-2020-26141)

    A flaw was found in ath10k_htt_rx_proc_rx_frag_ind_hl in drivers/net/wireless/ath/ath10k/htt_rx.c in the     Linux kernel WiFi implementations, where it accepts a second (or subsequent) broadcast fragments even when     sent in plaintext and then process them as full unfragmented frames. The highest threat from this     vulnerability is to integrity. (CVE-2020-26145)

    A flaw was found in ieee80211_rx_h_defragment in net/mac80211/rx.c in the Linux Kernel's WiFi     implementation. This vulnerability can be abused to inject packets or exfiltrate selected fragments when     another device sends fragmented frames, and the WEP, CCMP, or GCMP data-confidentiality protocol is used.
    The highest threat from this vulnerability is to integrity. (CVE-2020-26147)

    A flaw was found in the Linux kernel in certs/blacklist.c, When signature entries for EFI_CERT_X509_GUID     are contained in the Secure Boot Forbidden Signature Database, the entries are skipped. This can cause a     security threat and breach system integrity, confidentiality and even lead to a denial of service problem.
    (CVE-2020-26541)

    A vulnerability was found in the bluez, where Passkey Entry protocol used in Secure Simple Pairing (SSP),     Secure Connections (SC) and LE Secure Connections (LESC) of the Bluetooth Core Specification is vulnerable     to an impersonation attack where an active attacker can impersonate the initiating device without any     previous knowledge. (CVE-2020-26558)

    A flaw was found in the Linux kernel. Improper access control in BlueZ may allow an authenticated user to     potentially enable information disclosure via adjacent access. The highest threat from this vulnerability     is to data confidentiality and integrity. (CVE-2021-0129)

    A flaw was found in the Linux kernel's KVM implementation, where improper handing of the VM_IO|VM_PFNMAP     VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest.
    This flaw allows users who can start and control a VM to read/write random pages of memory, resulting in     local privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity,     and system availability. (CVE-2021-22543)

    A flaw was found in the Linux kernel's handling of the removal of Bluetooth HCI controllers. This flaw     allows an attacker with a local account to exploit a race condition, leading to corrupted memory and     possible privilege escalation. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-32399)

    A use-after-free flaw was found in hci_send_acl in the bluetooth host controller interface (HCI) in Linux     kernel, where a local attacker with an access rights could cause a denial of service problem on the system     The issue results from the object hchan, freed in hci_disconn_loglink_complete_evt, yet still used in     other places. The highest threat from this vulnerability is to data integrity, confidentiality and system     availability. (CVE-2021-33034)

    The canbus filesystem in the Linux kernel contains an information leak of kernel memory to devices on the     CAN bus network link layer.  An attacker with the ability to dump messages on the CAN bus is able to learn     of uninitialized stack values by dumbing messages on the can bus. (CVE-2021-34693)

    An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux     kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a     system crash or a leak of internal kernel information. The highest threat from this vulnerability is to     system availability. (CVE-2021-3506)

    A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the     system. (CVE-2021-3564)

    A flaw use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in     the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call     hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(),     hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system     or escalate their privileges on the system. (CVE-2021-3573)

    A flaw was found in the Linux kernels NFC implementation, A NULL pointer dereference and BUG leading to a     denial of service can be triggered by a local unprivileged user causing a kernel panic. (CVE-2021-38208)

    In the Linux kernel, the following vulnerability has been resolved:

    HID: usbhid: fix info leak in hid_submit_ctrl

    In hid_submit_ctrl(), the way of calculating the report length doesn'ttake into account that report->size     can be zero. When running thesyzkaller reproducer, a report of size 0 causes hid_submit_ctrl) tocalculate     transfer_buffer_length as 16384. When this urb is passed tothe usb core layer, KMSAN reports an info leak     of 16384 bytes.

    To fix this, first modify hid_report_len() to account for the zeroreport size case by using DIV_ROUND_UP     for the division. Then, call itfrom hid_submit_ctrl(). (CVE-2021-46906)
