Description SMASH SMASH 2024-07-05 12:14:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: v4l: async: Properly re-initialise notifier entry in unregister

The notifier_entry of a notifier is not re-initialised after unregistering
the notifier. This leads to dangling pointers being left there so use
list_del_init() to return the notifier_entry an empty list.
