Therefore, the freeing must also be done differently, explicitly NULL'ing it out after the free, since otherwise there's a nasty double-free bug here if a file fails to load after this has been parsed, and we get another free later (e.g. because no other file exists.) Fix that by adding the missing NULL assignment. [Fix] Mantic: Clean cherry-pick from linux-6.7.y Jammy: not-affected Focal: not-affected Bionic: not-affected Xenial: not-affected Trusty: not-affected [Test Case] Compile and boot tested. [Where problems could occur] This fix affects those who use iwlwifi (intel wireless wifi), an issue with this fix would be visable to the user via unpredicted system behavior or a system crash.
