CVE-2025-68354
N/A
Summary
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.
