High [CVE-2026-68427] Fix use-after-free in host1x_bo_clear_cached_mappings
CVE-2026-68427Source published Source updated
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. The `__host1x_bo_unpin()` function incorrectly dereferences a memory mapping after it has been freed, leading to a use-after-free vulnerability. This issue could allow a local attacker to cause memory corruption, potentially leading to a system crash (Denial of Service) or, in more severe scenarios, arbitrary code execution. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat…
