Severity CVSS v4.0:
Pending analysis
Type:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/panfrost: Job should reference MMU not file_priv<br /> <br /> For a while now it&amp;#39;s been allowed for a MMU context to outlive it&amp;#39;s<br /> corresponding panfrost_priv, however the job structure still references<br /> panfrost_priv to get hold of the MMU context. If panfrost_priv has been<br /> freed this is a use-after-free which I&amp;#39;ve been able to trigger resulting<br /> in a splat.<br /> <br /> To fix this, drop the reference to panfrost_priv in the job structure<br /> and add a direct reference to the MMU structure which is what&amp;#39;s actually<br /> needed.
