Subject: [PATCH wireless 0/2] wifi: brcmfmac: fwsignal: bound indices from firmware signals
Date: Mon, 16 Nov 2026 02:58:41 +0800 [thread overview]
Message-ID: <20261115185843.64633-1-maoyixie.tju@gmail.com> (raw)
These patches add bounds checks for indices that the device sends in the
BCDC firmware signals. Patch 1 covers the AMPDU reorder indices. Patch 2
covers the interface index of MACDESC_ADD. On USB, brcmfmac parses these
signals with the default module parameters.
Both bugs were found with a static analysis tool that we develop. A
userspace harness that compiles the fwsignal.c functions unchanged
reproduces them under sanitizers. No hardware was available for testing.
