Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved. The issue is related to the perf/x86/amd/core component, where the status variable, containing unhandled overflow bits, is not properly masked in some cases. This leads to a warning being displayed, specifically WARNING: CPU: 156 PID: 475601 at arch/x86/events/amd/core.c:972 amd pmu v2 handle irq+0x216/0x270. The problem occurs because the loop continues before the status bit is unset when x86 perf event set period() returns 0, causing an inconsistency where the "handled" counter is incremented but the status bit is not cleaned.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
