CVE-2026-53054
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk3th percentile — higher than 3% of all known CVEs
Summary
In the Linux kernel, a locking bug was found in the drm/msm driver's VM_BIND UNMAP operation. An incorrect argument caused objects involved in UNMAP operations not to be consistently locked, potentially leading to synchronization issues.
Risk Assessment
The risk involves potential data integrity corruption or system crashes due to improper memory access, especially for non-_NO_SHARE buffer objects.
Recommendation
Immediately update the Linux kernel to a version containing the fix (commit in drm/msm) or apply the patch from patchwork.freedesktop.org.
Original NVD description (English source)
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/
