Subject: [PATCH v2 0/3] platform/x86: dell-smbios-wmi: Fixes and cleanups
Date: Mon, 20 Jul 2026 15:19:18 +0200 [thread overview]
Message-ID: <20260720131921.368000-1-W_Armin@gmx.de> (raw)
This patch series primarily deals with a potential UAF inside
the dell-smbios-wmi driver reported by a user. The first patch
fixes this issue, with the remaining two patches further
cleaning up the resource management.
All patches have been tested on a Dell Inspiron 3505 and appear
to work. I also verified that the UAF issue does not occur anymore
after applying the first patch.
Changes since v1:
- move the rw semaphore next to wmi_list and add a comment
Armin Wolf (3):
platform/x86: dell-smbios-wmi: Fix chardev resource management
platform/x86: dell-smbios: Pass device to callbacks
platform/x86: dell-smbios-wmi: Replace global list with single item
