| CVE-2025-40276 | 0.00 | — | 0.00 | Dec 6, 2025 | In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Flush shmem writes before mapping buffers CPU-uncached The shmem layer zeroes out the new pages using cached mappings, and if we don't CPU-flush we might leave dirty cachelines behind, leading to potential data leaks and/or asynchronous buffer corruption when dirty cachelines are evicted. | |||
| CVE-2025-38596 | 0.00 | — | 0.00 | Aug 19, 2025 | In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Fix UAF in panthor_gem_create_with_handle() debugfs code The object is potentially already gone after the drm_gem_object_put(). In general the object should be fully constructed before calling drm_gem_handle_create(), except the debugfs tracking uses a separate lock and list and separate flag to denotate whether the object is actually initialized. Since I'm touching this all anyway simplify this by only adding the object to the debugfs when it's ready for that, which allows us to delete that separate flag. panthor_gem_debugfs_bo_rm() already checks whether we've actually been added to the list or this is some error path cleanup. v2: Fix build issues for !CONFIG_DEBUGFS (Adrián) v3: Add linebreak and remove outdated comment (Liviu) |
