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

  - powerpc/perf: Fix ref-counting on the PMU 'vpa_pmu' Commit 176cda0619b6 (powerpc/perf: Add perf interface     to expose vpa counters) introduced 'vpa_pmu' to expose Book3s-HV nested APIv2 provided L1<->L2 context     switch latency counters to L1 user-space via perf-events. However the newly introduced PMU named 'vpa_pmu'     doesn't assign ownership of the PMU to the module 'vpa_pmu'. Consequently the module 'vpa_pmu' can be     unloaded while one of the perf-events are still active, which can lead to kernel oops and panic of the     form below on a Pseries-LPAR: BUG: Kernel NULL pointer dereference on read at 0x00000058 <snip> NIP     [c000000000506cb8] event_sched_out+0x40/0x258 LR [c00000000050e8a4] __perf_remove_from_context+0x7c/0x2b0     Call Trace: [c00000025fc3fc30] [c00000025f8457a8] 0xc00000025f8457a8 (unreliable) [c00000025fc3fc80]     [fffffffffffffee0] 0xfffffffffffffee0 [c00000025fc3fcd0] [c000000000501e70] event_function+0xa8/0x120     <snip> Kernel panic - not syncing: Aiee, killing interrupt handler! Fix this by adding the module     ownership to 'vpa_pmu' so that the module 'vpa_pmu' is ref-counted and prevented from being unloaded when     perf-events are initialized. (CVE-2025-22094)
