- Summary
- CVE-2022-49359 affecting package kernel 5.15.200.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/panfrost: Job should reference MMU not file_priv
For a while now it's been allowed for a MMU context to outlive it's corresponding panfrostpriv, however the job structure still references panfrostpriv to get hold of the MMU context. If panfrost_priv has been freed this is a use-after-free which I've been able to trigger resulting in a splat.
To fix this, drop the reference to panfrost_priv in the job structure and add a direct reference to the MMU structure which is what's actually needed.
