CVE-2026-53264

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free (UAF) vulnerability, where the system attempts to use memory that has already been released. This could potentially allow an attacker to cause system instability or execute arbitrary code.

An Important severity race condition was discovered in the Linux kernel's net/sched action API. This presents the opportunity of a use-after-free, which could allow a local attacker to escalate privileges or cause a denial of service due to concurrent filter operations.
