      "title": "regulator: core: regulator_lock_two() should test for EDEADLK not EDEADLOCK",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nregulator: core: regulator_lock_two() should test for EDEADLK not EDEADLOCK\n\nCompare against -EDEADLK, which is what ww_mutex_lock() actually\nreturns and what every other deadlock check in this file already uses.\n\nFunction regulator_lock_two() acquires two regulators via\nregulator_lock_nested() -> ww_mutex_lock().  On contention,\nww_mutex_lock() returns -EDEADLK, which is the caller's signal to drop\nthe lock it holds and retry the acquisition in the canonical order.\n\nHowever, regulator_lock_two() tests the return value against -EDEADLOCK\nrather than -EDEADLK.  On most architectures, EDEADLK and EDEADLOCK are\nthe same value, so the comparison happens to be correct and the bug is\ninvisible.  But on MIPS, SPARC, and PowerPC, those two errors have\ndifferent values.  The test is wrong: a genuine -EDEADLK backoff no\nlonger matches -EDEADLOCK, so instead of unlocking and retrying, the\ncode falls into WARN_ON(ret) and returns with only one of the two\nregulators locked.\n\nIn practice, this is a bug only on MIPS, because the regulator core is\nnot built or used on the other two platforms.\n\nIn general, EDEADLK is preferred over EDEADLOCK for new code.",
