In the Linux kernel, the following vulnerability has been resolved:

regulator: core: Protect regulator_supply_alias_list with regulator_list_mutex

regulator_supply_alias_list was accessed without any locking in
regulator_supply_alias(), regulator_register_supply_alias(), and
regulator_unregister_supply_alias(). Concurrent registration,
unregistration and lookups can race, leading to:

1 use-after-free if an alias entry is removed while being read,
2 duplicate entries when two threads register the same alias,
3 inconsistent alias mappings observed by consumers.

Protect all traversals, insertions and deletions on
regulator_supply_alias_list with the existing regulator_list_mutex.
