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...
