{"id":"DEBIAN-CVE-2026-41256","details":"jq is a command-line JSON processor. In 1.8.1 and earlier, Top-level jq programs loaded from a file with -f are truncated at the first embedded NUL byte on current upstream HEAD. A crafted filter file such as . followed by \\x00 and arbitrary suffix compiles and executes as only the prefix before the NUL. This leaves jq with a post-CVE-2026-33948 prefix/full-buffer mismatch on the compilation path even though the JSON parser path has already been fixed.","modified":"2026-09-01T16:06:41.942643432Z","published":"2026-05-11T18:16:33.983Z","upstream":["CVE-2026-41256"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41256"}],"affected":[{"package":{"name":"jq","ecosystem":"Debian:12","purl":"pkg:deb/debian/jq?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6-2.1+deb12u2"}]}],"versions":["1.6-2.1","1.6-2.1+deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41256.json"}},{"package":{"name":"jq","ecosystem":"Debian:13","purl":"pkg:deb/debian/jq?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.1-6+deb13u3"}]}],"versions":["1.7.1-6+deb13u1","1.7.1-6+deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41256.json"}},{"package":{"name":"jq","ecosystem":"Debian:14","purl":"pkg:deb/debian/jq?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.1-6"}]}],"versions":["1.8.0-1","1.8.1-1","1.8.1-2","1.8.1-3","1.8.1-4","1.8.1-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41256.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
