CVE-2026-89753

A flaw was found in the Linux kernel's memory management subsystem. The shrinklruvec function, responsible for memory reclaim, fails to properly report Read-Copy-Update RCU task quiescent states on systems with preemption enabled. This can lead to RCU task stalls, causing system unresponsiveness ...

CVE-2026-89580

CVE-2026-89580 affects the Linux kernel BPF subsystem, specifically __bpf_get_stack(). The root cause is a preemption race : a preemptible BPF program (e.g., a non-sleepable raw tracepoint on a PREEMPT kernel) can be scheduled out between obtaining a per-CPU perf_callchain_entry buffer and copyin...
