CVE-2026-99143

A flaw was found in the Linux kernel's tracing subsystem. A local attacker could cause a Denial of Service (DoS) or memory corruption by exploiting an out-of-bounds memory access vulnerability during filter parsing. The predicate parsing mechanism improperly calculates boundary limits for event filter conditions, allowing parsing operations to exceed the allocated memory buffer. An attacker can exploit this issue by submitting a crafted filter expression to corrupt memory and crash the system.
