Overview
What is CVE-2026-98533?
In the Linux kernel, the following vulnerability has been resolved:
ipe: protect the dm-verity root hash with RCU
ipe_bdev_setintegrity() frees the old root hash when dm-verity publishes a new one on ->preresume, while policy evaluation can still be dereferencing it.
Protect the root hash with RCU. The evaluation path already runs under rcu_read_lock().
