Subject: [PATCH 0/4] USB: fix use-after-free on disconnect race
Date: Mon, 22 Jun 2026 17:26:08 +0200 [thread overview]
Message-ID: <20260622152612.116422-1-johan@kernel.org> (raw)
Mutexes cannot be used to manage lifetime of objects directly as the
mutex structure is accessed by mutex_unlock() after releasing the lock.
Note that the reporter of the iowarrior issue sent a fix last Friday
that I had missed. That one requires a bit of work still, though. [1]
