Subject: Re: [PATCH 1/2] ACPI: pfr_telemetry: keep the state until the last file is closed
Date: Mon, 09 Nov 2026 08:19:13 +0000 [thread overview]
Message-ID: <20261109081906.275540-2-ca@modelmiser.com> (raw)
In-Reply-To: <20261108233900.4043941-3-ca@modelmiser.com>
Shuangpeng Bai reported this bug in June, with a reproducer, and I missed
the report when I sent this patch. It is the same use-after-free after an
unbind with the file still open.
Reported-by: Shuangpeng Bai <shuangpeng.kernel@gmail.com>
Closes: https://lore.kernel.org/all/178144969601.60470.3508974301899957212@gmail.com/
