{"id":"CVE-2026-40026","summary":"Sleuth Kit ISO9660 SUSP Extension Reference Out-of-Bounds Read","details":"The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the ISO9660 filesystem parser where the parse_susp() function trusts len_id, len_des, and len_src fields from the disk image to memcpy data into a stack buffer without verifying that the source data falls within the parsed SUSP block. An attacker can craft a malicious ISO image that causes reads past the end of the SUSP data buffer, and a zero-length SUSP entry can trigger an infinite parsing loop.","modified":"2026-07-08T08:13:08.826636668Z","published":"2026-04-08T21:35:22.278Z","database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40026.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40026.json"},{"type":"ADVISORY","url":"https://mobasi.ai/sentinel"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40026"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/sleuth-kit-iso9660-susp-extension-reference-out-of-bounds-read"},{"type":"REPORT","url":"https://github.com/sleuthkit/sleuthkit/pull/3445"},{"type":"FIX","url":"https://github.com/sleuthkit/sleuthkit/commit/a95b0ac21733b059a517aaefa667a17e1bcbdee1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sleuthkit/sleuthkit","events":[{"introduced":"0"},{"fixed":"c6efd66293546b9c95637be703c7c7823e950629"},{"fixed":"a95b0ac21733b059a517aaefa667a17e1bcbdee1"}],"database_specific":{"cpe":"cpe:2.3:a:sleuthkit:the_sleuth_kit:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"4.14.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["ct-3.15.0","sleuthkit-4.14.0","ct-3.13.0","ct-3.12.0","ct-3.9.0","ct-3.6.0","sleuthkit-4.12.0","ct-3.5.0","sleuthkit-4.6.3","sleuthkit-4.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40026.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
