AlmaLinux 9.2 主機已安裝的套件會受到 TuxCare ALMALINUX9.2：CLSA-2026：1767864313 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails When scpi probe fails, at any point, we need to ensure that the scpi_info is not set and will remain NULL until the probe succeeds. If it is not taken care, then it could result use-after-free as the value is exported via get_scpi_ops() and could refer to a memory allocated via devm_kzalloc() but freed when the probe fails. (CVE-2022-50087)

  - 已解決 Linux 核心中的下列弱點：wifi: rtlwifi: Fix global-out-of-bounds bug in _rtl8812ae_phy_set_txpower_limit() There is a global-out-of-bounds reported by KASAN: BUG:
    KASAN: global-out-of-bounds in _rtl8812ae_eq_n_byte.part.0+0x3d/0x84 [rtl8821ae] Read of size 1 at addr ffffffffa0773c43 by task NetworkManager/411 CPU: 6 PID: 411 Comm: NetworkManager Tainted: G D 6.1.0-rc8+ #144 e15588508517267d37 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), Call Trace: <TASK> ...

    </TASK> The root cause of the problem is that the comparison order of prate_section in
    _rtl8812ae_phy_set_txpower_limit() is wrong. The _rtl8812ae_eq_n_byte() is used to compare the first n bytes of the two strings from tail to head, which causes the problem. In the
    _rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet this requirement by carefully designing the comparison order. For example, pregulation and pbandwidth are compared in order of length from small to large, first is 3 and last is 4. However, the comparison order of prate_section dose not obey such order requirement, therefore when prate_section is HT, when comparing from tail to head, it will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As mentioned above, the
    _rtl8812ae_eq_n_byte() has the same function as strcmp(), so just strcmp() is enough. Fix it by removing
    _rtl8812ae_eq_n_byte() and use strcmp() barely. Although it can be fixed by adjusting the comparison order of prate_section, this may cause the value of rate_section to not be from 0 to 5. In addition, commit 21e4b0726dc6 not only moved driver from staging to regular tree, but also added setting txpower limit function during the driver config phase, so the problem was introduced by this commit. (CVE-2022-50279)

  - 已解決 Linux 核心中的下列弱點：wifi: ath11k: fix monitor mode bringup crash When the interface is brought up in monitor mode, it leads to NULL pointer dereference crash. This crash happens when the packet type is extracted for a SKB. This extraction which is present in the received msdu delivery path,is not needed for the monitor ring packets since they are all RAW packets.
    Hence appending the flags with RX_FLAG_ONLY_MONITOR to skip that extraction.

  - 已解決 Linux 核心中的下列弱點：PCI: Fix pci_device_is_present() for VFs by checking PF pci_device_is_present() previously didn't work for VFs because it reads the Vendor and Device ID, which are 0xffff for VFs, which looks like they aren't present. Check the PF instead. Wei Gong reported that if virtio I/O is in progress when the driver is unbound or 0 is written to /sys/.../sriov_numvfs, the virtio I/O operation hangs, which may result in output like this: task:bash state:D stack: 0 pid: 1773 ppid: 1241 flags:0x00004002 Call Trace: schedule+0x4f/0xc0 blk_mq_freeze_queue_wait+0x69/0xa0 blk_mq_freeze_queue+0x1b/0x20 blk_cleanup_queue+0x3d/0xd0 virtblk_remove+0x3c/0xb0 [virtio_blk] virtio_dev_remove+0x4b/0x80 ... device_unregister+0x1b/0x60 unregister_virtio_device+0x18/0x30 virtio_pci_remove+0x41/0x80 pci_device_remove+0x3e/0xb0 This happened because pci_device_is_present(VF) returned false in virtio_pci_remove(), so it called virtio_break_device(). The broken vq meant that vring_interrupt() skipped the vq.callback() that would have completed the virtio I/O operation via virtblk_done().

To simply fix it, we could just pass @sign kmalloc'd from crypt_message() and then we're done. Luckily, we don't seem to pass any other vmalloc'd buffers in smb_rqst::rq_iov... Instead, let's map the correct pages and offsets from vmalloc buffers as well in cifs_sg_set_buf() and then avoiding such oopses. (CVE-2022-50341)

Thus acpi_ds_get_current_walk_state() called by acpi_ps_parse_aml() subsequently returns it as the new walk state which is incorrect. To address this, make acpi_ds_call_control_method() call acpi_ds_pop_walk_state() to pop next_walk_state from the thread before returning an error.

Function init_var_ref() allocates the corresponding fields such as ref_field->system, but frees these fields when the function encounters an error. The caller later calls destroy_hist_field() to conduct error handling, which frees the fields and the variable itself. This results in double free of the fields which are already freed in the previous function. Fix this by storing NULL to the corresponding fields when they are freed in init_var_ref().

  - Linux PV 裝置前端容易受到後端攻擊 [其 CNA 資訊記錄與多個 CVE 有關；文字說明了哪些方面/弱點對應哪個 CVE。] 數個 Linux PV 裝置前端正在以易受爭用情形影響的方式，使用授權表介面移除後端的存取權，進而可能導致資料洩漏、惡意後端損毀資料以及惡意後端觸發拒絕服務：blkfront、netfront、scsifront 和 gntalloc 驅動程式正在測試授權參照是否仍在使用中。如果情況並非如此，則它們會假設後續每次都能移除授予的存取權；但如果後端已在執行這兩項作業之間對應授權頁面，則此假設不成立。因此，無論前端 I/O 完成後如何使用頁面，後端都可以繼續存取客體的記憶體頁面。
    xenbus 驅動程式有一個類似的問題，因為它不會檢查是否成功移除向共用環形緩衝區授予的存取權。blkfront：CVE-2022-23036 netfront：CVE-2022-23037 scsifront：CVE-2022-23038 gntalloc：CVE-2022-23039 xenbus：CVE-2022-23040 blkfront、netfront、scsifront、usbfront、dmabuf、xenbus、9p、kbdfront 和 pvcalls 使用功能延遲釋放授權參照 (直到不再使用這個參照)，但相關資料頁面的釋放與刪除授予的存取權並不同步。因此，即使在記憶體頁面被釋放並重新用於其他目的之後，後端仍可繼續存取該頁面。CVE-2022-23041 如果 netfront 無法撤銷 rx 路徑中的存取權，則 BUG_ON() 宣告將失敗。這會導致客體發生拒絕服務 (DoS) 情形，而此情形可能由後端觸發。CVE-2022-23042 (CVE-2022-23042)
