Subject: [PATCH] lib/inflate: fix memory leak in inflate_fixed() on inflate_codes() failure
Date: Fri, 6 Mar 2026 16:16:12 +0000 [thread overview]
Message-ID: <20260306161612.2811703-1-objecting@objecting.org> (raw)
When inflate_codes() fails in inflate_fixed(), only the length list 'l'
is freed, but the Huffman tables 'tl' and 'td' are leaked. Add the
missing huft_free() calls on the error path.
