CVE-2026-24823Network attack vector

Memory corruption via oversized gzip extra field

Published Jan 27, 2026 · Updated Jan 27, 2026

Out-of-bounds write in X-TRACK 2.7 and earlier allows remote attackers to corrupt memory through crafted gzip header data. The cloned zlib inflate() code copies a gzip extra field across multiple calls without limiting the total bytes to the caller-provided buffer. Reaching the flaw requires X-TRACK to decode attacker-controlled compressed image data, and memory corruption can crash the device or alter execution.
