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.
