CVE-2026-37531 is a critical-severity flaw (CVSS 9.8) affecting automotive grade linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

AGL app-framework-main thru 17.1.12 contains a Zip Slip path traversal vulnerability (CWE-22) combined with a TOCTOU race condition (CWE-367) in the widget installation flow. The is_valid_filename function in wgtpkg-zip.c validates ZIP entry names but does not check for dot notation directory traversal sequences it only blocks absolute paths. The zread extraction function uses openat(workdirfd, filename, O_CREAT) which resolves dot notation value
