Estado: RecibidaSin puntuar—

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.
