Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s perf/x86 component related to handling PEBS records and interrupt throttling. Specifically, when the
intel pmu drain pebs icl() function processes the last PEBS record, the perf event overflow() function can trigger interrupt throttling, which clears event pointers in the cpuc->events[] array to NULL. Subsequently, attempting to process another PEBS record can lead to a NULL pointer access. This occurs because clearing the event pointers happens in x86 pmu stop(), and moving this operation to x86 pmu del() resolves the issue.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
