CVE-2026-68427

7.8 HIGH 0.1% exploit odds No fix listed Memory safety OS & kernel

What it is

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.
