CVE-2026-64250

CVE-2026-64250 affects the Linux kernel on LoongArch. The issue arises when smp_send_stop() parks secondary CPUs and marks them offline without informing RCU, causing RCU to expect quiescent states from CPUs that are effectively stopped. This can lead to RCU grace period stalls, especially after ...

CVE-2026-64211

The CVE-2026-64211 entry concerns the Linux kernel, specifically Tree SRCU behavior during CPU online/offline transitions. The concrete issue is that, while an srcu_struct is switching to an all-CPUs state, callbacks could be invoked for CPUs that have never been online or may never come online (...

CVE-2026-64210

Summary of CVE-2026-64210 (Linux kernel, net/mlx5e/xsk): The vulnerability arises from unlocking writes to the ICOSQ during NAPI polling when CPU affinity changes while XSK work remains. Two races are described: A) mlx5e_trigger_irq() executes on the old CPU after napi_complete_done() while mlx5e...
