CVE-2025-68354

/// Technical description

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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
