AlmaLinux 9.2 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.2：CLSA-2024：2024：1725293298 1 公告中提及的多个漏洞的影响。

  - 在采用设备文件“/dev/dri/renderD128（或 Dxxx）”的 Linux 内核中，在 GPU 组件的 drivers/gpu/vmxgfx/vmxgfx_execbuf.c 中的 vmwgfx 驱动程序中发现空指针取消引用漏洞。在系统中具有用户帐户的本地攻击者可利用此缺陷获得特权，造成拒绝服务 (DoS)。
    (CVE-2022-38096)

  - 已修复 Linux 内核中的下列漏洞：bnxt: prevent skb UAF after handing over to PTP worker When reading the timestamp is required bnxt_tx_int() hands over the ownership of the completed skb to the PTP worker. The skb should not be used afterwards, as the worker may run before the rest of our code and free the skb, leading to a use-after-free. Since dev_kfree_skb_any() accepts NULL make the loss of ownership more obvious and set skb to NULL. (CVE-2022-48637)

  - 在 6.5.9 版之前在 Linux 内核中发现了一个问题，具有对 MMIO 寄存器的用户空间访问权限的本地用户可利用此漏洞。#VC 处理程序中的不正确访问检查和 MMIO 访问的 SEV-ES 模拟的指令模拟可能会导致对内核内存的任意写入访问（从而导致特权提升）。此问题依赖于竞争条件触发，通过该竞争条件，用户空间可以在 #VC 处理程序读取指令之前替换该指令。(CVE-2023-46813)

  - 已修复 Linux 内核中的下列漏洞：PM / devfreq: Synchronize devfreq_monitor_[start/stop] There is a chance if a frequent switch of the governor done in a loop result in timer list corruption where timer cancel being done from two place one from cancel_delayed_work_sync() and followed by expire_timers() can be seen from the traces[1]. while true do echo simple_ondemand > /sys/class/devfreq/1d84000.ufshc/governor echo performance > /sys/class/devfreq/1d84000.ufshc/governor done It looks to be issue with devfreq driver where device_monitor_[start/stop] need to synchronized so that delayed work should get corrupted while it is either being queued or running or being cancelled.
    Let's use polling flag and devfreq lock to synchronize the queueing the timer instance twice and work data being corrupted.

  - 已修复 Linux 内核中的下列漏洞：sched/psi: Fix use-after-free in ep_remove_wait_queue() If a non-root cgroup gets removed when there is a thread that registered trigger and is polling on a pressure file within the cgroup, the polling waitqueue gets freed in the following path: do_rmdir cgroup_rmdir kernfs_drain_open_files cgroup_file_release cgroup_pressure_release psi_trigger_destroy However, the polling thread still has a reference to the pressure file and will access the freed waitqueue when the file is closed or upon exit: fput ep_eventpoll_release ep_free ep_remove_wait_queue remove_wait_queue This results in use-after-free as pasted below. The fundamental problem here is that cgroup_file_release() (and consequently waitqueue's lifetime) is not tied to the file's real lifetime. Using wake_up_pollfree() here might be less than ideal, but it is in line with the comment at commit 42288cb44c4b (wait: add wake_up_pollfree()) since the waitqueue's lifetime is not tied to file's one and can be considered as another special case. While this would be fixable by somehow making cgroup_file_release() be tied to the fput(), it would require sizable refactoring at cgroups or higher layer which might be more justifiable if we identify more cases like this.
