of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: lib/inflate: fix memory leak in inflate_dynamic() on inflate_codes() failure
Date: Fri, 6 Mar 2026 16:16:47 +0000

When inflate_codes() fails in inflate_dynamic(), the code jumps to the
'out' label which only frees 'll', leaking the Huffman tables 'tl' and
'td'.  Restructure the code so that the decoding tables are always freed
before reaching the 'out' label.
