In the Linux kernel, the following vulnerability has been resolved: 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
