CVE-2026-89903

CVE-2026-89903 affects the Linux kernel on the LoongArch architecture, specifically the rethook trampoline (previously the kretprobe trampoline since v6.3 ). The trampoline incorrectly saves and restores $r21 (the per-CPU base register) across its entry/exit frame. If a task migrates CPUs between...
