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

drm/vmwgfx: Fix Use-after-free in validation

Nodes stored in the validation duplicates hashtable come from an arena allocator that is cleared at the end of vmw_execbuf_process. All nodes are expected to be cleared in vmw_validation_drop_ht but this node escaped because its resource was destroyed prematurely.
