## Overview

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.

Perform both under bridge_lock.

## Affected

- `Linux >= 17805a15d1751f5d6bb06f924f9bed216feb8db7 < f469d850854101eae60dd4080244f114a9bcf2b5`
- `Linux >= 17805a15d1751f5d6bb06f924f9bed216feb8db7 < b62e3db8cdc1680e1c3390591e872f485148541a`
- `Linux 6.19`
