Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-06-28 09:31

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Fix VM_BIND UNMAP locking

Wrong argument meant that the objs involved in UNMAP ops were not always getting locked.

Since _NO_SHARE objs share a common resv with the VM (which is always locked) this would only show up with non-_NO_SHARE BOs.

Patchwork: https://patchwork.freedesktop.org/patch/713898/

Severity

7.8 (High)
