On an MT7621 or an MT7531 both pointers\nare still NULL from devm_kzalloc(), so rmmod or a sysfs unbind calls\nregulator_disable() on NULL.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/62c0e38b2e5034184d4502ce77bd178b29e59b83","tags":[]},{"url":"https://git.kernel.org/stable/c/aae2a1f1e3a0ac5eeb439262a2328a2a392413ac","tags":[]},{"url":"https://git.kernel.org/stable/c/bd172580e624bac00d83abd5c4320d2e14d853bc","tags":[]},{"url":"https://git.kernel.org/stable/c/c2cdef41e0b4d8ed23a5b41e6ad4e64594e055e4","tags":[]},{"url":"https://git.kernel.org/stable/c/e9a5298532780ecdd05c3220f3e1e3067b3537c3","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
