CVE-2026-53054
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
