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 ...
