Subject: Re: [PATCH] wifi: b43: fix use-after-free in b43_bcma_remove()
Date: Tue, 13 Oct 2026 02:16:04 +0200	[thread overview]
Message-ID: <20261013001604.49954-1-gonsolo@gmail.com> (raw)
In-Reply-To: <20261013000124.48605-1-gonsolo@gmail.com>

Adding the people the CI bot listed as not CCed (b43 author and others
working on b43), for information. No changes to the patch.

The bug is in mainline: b43_bcma_remove() reads wldev->dev after
b43_one_core_detach() has freed wldev. b43_ssb_remove() already takes a
copy, so the patch does the same.
