CVE-2026-80916
A flaw was found in the Linux kernel's kcov component. A race condition occurs in PREEMPTRT kernels when softirq handlers, running as preemptible task threads, are preempted by higher-priority softirq threads on the same CPU. This can lead to data corruption of the KCOV state, kernel crashes, and...
