CVE-2026-74594

CVE-2026-74594 affects the Linux kernel's PSI (Pressure Stall Information) subsystem . A race condition exists between psi_schedule_rtpoll_work(), called locklessly from the scheduler hotpath, and psi_trigger_destroy(), which tears down the last rtpoll trigger under lock. The rtpoll_timer can be ...
