CVE-2026-89753

CVE-2026-89753 affects the Linux kernel in the memory management subsystem (mm/vmscan ). The root cause is that the scan loop in shrink_lruvec() only calls cond_resched(), which is a no-op on PREEMPTION kernels . Since involuntary preemption does not count as a Tasks-RCU quiescent state , a recla...
