Description
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. [FW: remove model name according to latest guideline]
