CVE-2024-53080

Summary

CVE-2024-53080 is a vulnerability affecting the Linux kernel. It involves the drm/panthor subsystem, where retrieving vm pointers from the XArray required improved synchronization. Similar to a previous commit, the solution involves utilizing the XArray's internal locking mechanism when accessing its entries. A prior attempt to protect fetching heap pointers from XArray has been removed, as this operation is already protected by the @pool->lock.
