{"id":"DEBIAN-CVE-2026-30656","details":"A NULL pointer dereference vulnerability exists in fio (Flexible I/O Tester) v3.41 when parsing job files containing the fdp_pli option. The callback function str_fdp_pli_cb() does not validate the input pointer and calls strdup() on a NULL value when the option is specified without an argument. This results in a segmentation fault and process crash.","modified":"2026-09-14T17:03:03.386303758Z","published":"2026-04-16T15:17:17.873Z","upstream":["CVE-2026-30656"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-30656"}],"affected":[{"package":{"name":"fio","ecosystem":"Debian:12","purl":"pkg:deb/debian/fio?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.33-3","3.35-1","3.35-2","3.35-3","3.35-4","3.36-1","3.37-1","3.38-1","3.39-1","3.41-1","3.41-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-30656.json"}},{"package":{"name":"fio","ecosystem":"Debian:13","purl":"pkg:deb/debian/fio?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.39-1","3.41-1","3.41-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-30656.json"}},{"package":{"name":"fio","ecosystem":"Debian:14","purl":"pkg:deb/debian/fio?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.39-1","3.41-1","3.41-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-30656.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
