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

  - perf/core: Fix system hang caused by cpu-clock usage cpu-clock usage by the async-profiler tool can     trigger a system hang, which got bisected back to the following commit by Octavia Togami: 18dbcbfabfff     (perf: Fix the POLL_HUP delivery breakage) causes this issue The root cause of the hang is that cpu-     clock is a special type of SW event which relies on hrtimers. The __perf_event_overflow() callback is     invoked from the hrtimer handler for cpu-clock events, and __perf_event_overflow() tries to call     cpu_clock_event_stop() to stop the event, which calls htimer_cancel() to cancel the hrtimer. But that's a     recursion into the hrtimer code from a hrtimer handler, which (unsurprisingly) deadlocks. To fix this bug,     use hrtimer_try_to_cancel() instead, and set the PERF_HES_STOPPED flag, which causes     perf_swevent_hrtimer() to stop the event once it sees the PERF_HES_STOPPED flag. [ mingo: Fixed the     comments and improved the changelog. ] (CVE-2025-40327)

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