Description
A flaw was found in the Linux kernel. A local user can cause a Denial of Service (DoS) by exhausting the pending signal queue limit. Due to an issue where resource limits are enforced unconditionally even for signals intended to override them, the kernel fails to allocate necessary resources when delivering critical signals with their metadata. This prevents applications from properly receiving fault information, leading to unexpected application crashes or unstable behavior.
