CVE-2026-74594

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

Description A race condition exists between psi schedule rtpoll work() and psi trigger destroy(). Because psi schedule rtpoll work() is called locklessly from the scheduler hotpath, it can conflict with the destruction of the last rtpoll trigger. This allows a timer to be re-armed while the group is being freed, leading to a situation where the function poll timer fn() executes on freed memory.

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