A flaw was found in the Linux kernel's Integrity Policy Enforcement (IPE) subsystem. A local attacker can cause a denial of service (DoS) or potentially execute arbitrary code by triggering a race condition during policy management. This issue occurs when a newly loaded policy is audited after internal locks are released, allowing a concurrent deletion request to free the memory while it is still being accessed.
