Subject: [PATCH v4 0/3] media: meson: Fix memory leak in error path in
Date: Thu, 21 May 2026 13:04:10 +0530 [thread overview]
Message-ID: <20260521073449.10057-1-linux.amoon@gmail.com> (raw)
Following chamges try to fix the memory leak reported by Sashiko
Pre-existing issues:
- [Critical] The `sess->esparser_queue_work` work item is not canceled
before freeing the session context, leading to a potential Use-After-Free
vulnerability.
- [High] The patch attempts to fix a memory leak reported by kmemleak,
but misdiagnoses the root cause and leaves the primary memory leak
(the V4L2 control handler) unresolved.
- [High] The driver does not verify if `kthread_run()` returns an `ERR_PTR`,
leading to a kernel panic when `kthread_stop()` is called.
Reported-by: Sashiko <sashiko-bot@kernel.org>
Closes: https://lore.kernel.org/all/20260520045905.6ACBA1F000E9@smtp.kernel.org/#t
Thanks
-Anand
