The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.
