CVE-2022-49359

Summary

CVE-2022-49359 is a vulnerability affecting the Linux kernel. This issue stems from the drm/panfrost driver, where a job's structure continues to reference panfrost_priv even after it has been freed. This results in a use-after-free scenario, which can be exploited to cause a splat. To mitigate this vulnerability, the direct reference to panfrost_priv in the job structure has been removed, and a reference to the MMU structure, which is the actual requirement, has been added instead.
