fkie_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().

[FW: remove model name according to latest guideline]
