CVE-2026-23311

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.15.0-next-20250530-next-20250530 #1

Description The Linux kernel contains a flaw in the event scheduling within the perf/core component, specifically in the ctx sched in() function. Lockdep detected a bug where an invalid wait context occurs when a pinned event fails and attempts to wake up threads in the ring buffer. This issue arises from attempting to acquire a wait-queue lock while holding a perf-context lock, which is incorrect. The fix involves using irq work to address this synchronization problem.

Recommendations Update the Linux kernel to version 6.15.0-next-20250530-next-20250530 #1 or a later version to resolve this issue.
