| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel driver for HiSilicon performance monitoring unit (PMU) contained a flaw where the
perf pmu migrate context function could migrate the performance context to a CPU that was in the process of being taken offline. This occurred because the cpuhp::teardown() callback was called before the cpu online mask() was updated, leading to a potential crash. The issue was addressed by using the cpumask any but() function to ensure the context was migrated to an active CPU. The call trace provided indicates a potential issue within the mutex lock function during the context migration process.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
