Description OSIDB Bzimport 2026-06-24 18:06:52 UTC 
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.
