CVE-2026-76844

zlib 1.2.11 through 1.3.2 contains a heap buffer overflow: after an underlying write fails, gzwrite returns without resetting strm.nextin, leaving it pointed at the caller's buffer. A later gz write call then derives a position from the stale pointer and writes past a heap allocation; any write...
