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.

    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in the Linux kernel's Direct Rendering Manager (DRM) subsystem, specifically within the Qualcomm Adreno GPU (MSM) driver. An incorrect argument in the `VM_BIND UNMAP` locking mechanism meant that certain objects involved in unmapping operations were not consistently locked. This could potentially lead to unexpected system behavior or instability, particularly with non-shared buffer objects, impacting system reliability.
