Doc Text:	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.

Description OSIDB Bzimport 2026-10-18 15:32:03 UTC

In the Linux kernel, the following vulnerability has been resolved:

ipe: fix use-after-free when auditing a newly loaded policy

new_policy() audits the policy after ipe_new_policyfs_node() publishes it
and drops the new directory's inode lock. A concurrent delete can free
the policy while ipe_audit_policy_load() is still using it.

Audit the successful load under that lock.
