Description OSIDB Bzimport 2026-08-10 12:30:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/gpusvm: Fix MM reference leak in drm_gpusvm_range_evict

If kvmalloc_array() fails in drm_gpusvm_range_evict(), the MM
reference acquired earlier is not released, resulting in a reference
leak.

Fix this by dropping the MM reference on the kvmalloc_array()
failure path.
