CVE-2026-68427
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.13%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
