Overview
What is CVE-2026-98973?
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: Fix unlocked list_del in drm_bridge_add()
When re-adding a bridge that was previously removed, drm_bridge_add() drops it from bridge_lingering_list without holding bridge_lock.
Both bridge_list and bridge_lingering_list are protected by bridge_lock, as they are concurrently modified by drm_bridge_remove() and __drm_bridge_free(), and walked by the debugfs 'bridges' file. Running the list_empty() test and the list_del_init() outside of the lock may therefore corrupt either list.
