Subject: [PATCH 0/2] ipe: fix two use-after-frees
Date: Tue, 22 Sep 2026 20:13:47 -0700	[thread overview]
Message-ID: <20260923031349.1216431-1-wufan@kernel.org> (raw)

This series fixes two use-after-free bugs in IPE, both found by a recent
AI-assisted code scan.

The first one is in the policy load audit path, where a concurrent
delete can free the policy while it is being audited. The second one is
in the dm-verity root hash path, where ->preresume can free a digest
that policy evaluation is still using.

Fan Wu (2):
  ipe: fix use-after-free when auditing a newly loaded policy
  ipe: protect the dm-verity root hash with RCU
