Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The perf fuzzer identified a hard-lockup crash on a RaptorLake machine due to an issue in the
icl update topdown event() function. This crash occurs because the function is incorrectly invoked on E-core CPUs that do not support the perf metrics feature. The root cause is a regression introduced by a previous commit that mistakenly used the is topdown event() function instead of is topdown count() to determine whether to invoke topdown functions for the perf metrics feature.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
