Subject: [PATCH v4 0/2] wifi: libertas: fix two OOB reads from firmware fields
Date: Mon, 4 May 2026 19:14:50 +0000 [thread overview]
Message-ID: <20260504191452.3408257-1-tristan@talencesecurity.com> (raw)
Two fixes for out-of-bounds reads in libertas caused by unchecked
firmware-supplied fields.
Changes since v3:
- Use size_add() instead of raw addition/subtraction in bounds checks
to avoid integer wrapping on 32-bit (Dan Carpenter / kernel test robot)
Tristan Madani (2):
wifi: libertas: fix OOB read from firmware pkt_ptr offset in RX path
wifi: libertas: fix OOB read from firmware bssdescriptsize in scan
