# Linux kernel IPE: use-after-free when auditing a newly loaded policy

In the Linux kernel's IPE policy code, a newly loaded policy can be freed by a concurrent delete while it is still being audited. The sources describe a use-after-free, which can crash the kernel or be turned into memory corruption.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
