CVE-2026-72314: regulator: core: regulator_lock_two() should test for EDEADLK not EDEADLOCK

Published Aug 15, 2026
·
Updated

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

regulator: core: regulatorlocktwo() should test for EDEADLK not EDEADLOCK

Compare against -EDEADLK, which is what wwmutexlock() actually returns and what every other deadlock check in this file already uses.

Function regulatorlocktwo() acquires two regulators via regulatorlocknested() -> wwmutexlock(). On contention, wwmutexlock() returns -EDEADLK, which is the caller's signal to drop the lock it holds and retry the acquisition in the canonical order.

However, regulatorlocktwo() tests the return value against -EDEADLOCK rather than -EDEADLK. On most architectures, EDEADLK and EDEADLOCK are the same value, so the comparison happens to be correct and the bug is invisible. But on MIPS, SPARC, and PowerPC, those two errors have different values. The test is wrong: a genuine -EDEADLK backoff no longer matches -EDEADLOCK, so instead of unlocking and retrying, the code falls into WARNON(ret) and returns with only one of the two regulators locked.

In practice, this is a bug only on MIPS, because the regulator core is not built or used on the other two platforms.

In general, EDEADLK is preferred over EDEADLOCK for new code.

  67. Compensating control

    In the Linux kernel regulator core, change regulator_lock_two() to compare the regulator_lock_nested() / ww_mutex_lock() return value against -EDEADLK rather than -EDEADLOCK, so contention triggers unlocking and retry in canonical order; this is required in practice on MIPS.
