Description

In the Linux kernel, the following vulnerability has been resolved:

drm/panthor: Lock XArray when getting entries for the VM

Similar to commit cac075706f29 ("drm/panthor: Fix race when converting
group handle to group object") we need to use the XArray's internal
locking when retrieving a vm pointer from there.

v2: Removed part of the patch that was trying to protect fetching
the heap pointer from XArray, as that operation is protected by
the @pool->lock.
