CVE-2026-53180

A flaw was found in the Linux kernel's timer migration handling. An incorrect assumption in the tmigrhandleremotecpu function regarding local softirq path handling of CPU timers can lead to a livelock. This occurs when a timer expires after the local timer wheel advances but before remote handlin...

CVE-2026-53180

The CVE concerns the Linux kernel timers/migration code. The root cause is that tmigr_handle_remote_cpu() skipped timer_expire_remote() when cpu == smp_processor_id(), assuming the local softirq path already handled this CPU’s timers. Because jiffies can advance after handling the local/global ti...
