Official Description

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.

Technical Analysis

CVE-2026-53054 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
