CentOS Linux 8.5 主机上存在安装的程序包，该程序包受到 TuxCare CENTOS8.5：CLSA-2026：U 1783789559公告中提及的漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：rtmutex: Use waiter::task instead of current in remove_waiter() remove_waiter() is used by the slowlock paths, but it is also used for proxy-lock rollback in rt_mutex_start_proxy_lock() when invoked from futex_requeue(). In the latter case waiter::task is not current, but remove_waiter() operates on current for the dequeue operation. That results in several problems: 1) the rbtree dequeue happens without waiter::task::pi_lock being held 2) the waiter task's pi_blocked_on state is not cleared, which leaves a dangling pointer primed for UAF around.
    3) rt_mutex_adjust_prio_chain() operates on the wrong top priority waiter task Use waiter::task instead of current in all related operations in remove_waiter() to cure those problems. [ tglx: Fixup rt_mutex_adjust_prio_chain(), add a comment and amend the changelog ] (CVE-2026-43499)

请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
