What to Know

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

gpu: host1x: Fix use-after-free in host1x_bo_clear_cached_mappings

__host1x_bo_unpin() drops the last reference to the mapping and frees

it, so we can't dereference mapping afterwards. The cache itself

outlives the mapping, so use the cache local variable instead. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
