CVE-2026-93222

A flaw was found in the Linux kernel's signal handling subsystem. When dispatching signals to a group of processes across different namespaces, the kernel modified shared signal metadata in place rather than copying it for each recipient. A local user could exploit this behavior to cause recipien...

kernel: signal: Prevent exec() race

A flaw was found in the Linux kernel's signal handling subsystem. A race condition occurs during process execution when managing pending timer signals, allowing the system to reference memory after it has been released. A local attacker could exploit this use-after-free flaw to achieve privilege...
