Subject: [PATCH 0/2] Fix out-of-bounds potential in decode_base64 and add regression tests
Date: Mon, 01 Dec 2025 15:09:17 +0100 [thread overview]
Message-ID: <20251201-base64-bounds-v1-0-3ae2b2e8b7cb@pengutronix.de> (raw)
I took a closer look at decode_base64 while reviewing coverity report
584740 (Out-of-bounds access). 1/2 resolves the issue (although coverity
seems to suspect an out-of-bounds access for the wrong reason and might
keep doing so), 2/2 adds a selftest I used to debug the issue.
