{"id":"UBUNTU-CVE-2026-40026","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":"2026-05-20T16:25:38.733814676Z","published":"2026-04-08T22:16:00Z","upstream":["CVE-2026-40026"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-40026"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-40026"},{"type":"REPORT","url":"https://github.com/sleuthkit/sleuthkit/pull/3445"},{"type":"REPORT","url":"https://github.com/sleuthkit/sleuthkit/commit/a95b0ac21733b059a517aaefa667a17e1bcbdee1"},{"type":"REPORT","url":"https://mobasi.ai/sentinel"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/sleuth-kit-iso9660-susp-extension-reference-out-of-bounds-read"}],"affected":[{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.3-2ubuntu1","3.2.3-2ubuntu2","3.2.3-2.1","3.2.3-2.2","3.2.3-2.2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.2.3-2.2ubuntu0.1~esm1","binary_name":"libtsk3-3"},{"binary_version":"3.2.3-2.2ubuntu0.1~esm1","binary_name":"sleuthkit"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.1.3-11ubuntu2","4.1.3-12ubuntu1","4.2.0-3","4.2.0-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtsk13","binary_version":"4.2.0-3ubuntu0.1~esm1"},{"binary_version":"4.2.0-3ubuntu0.1~esm1","binary_name":"sleuthkit"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.4.2-1","4.4.2-3"],"ecosystem_specific":{"binaries":[{"binary_version":"4.4.2-3","binary_name":"libtsk13"},{"binary_version":"4.4.2-3","binary_name":"sleuthkit"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.6.5-1","4.6.7-1","4.6.7-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtsk13","binary_version":"4.6.7-1build1"},{"binary_name":"sleuthkit","binary_version":"4.6.7-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.10.1+dfsg-1","4.11.0+dfsg-1","4.11.1+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtsk19","binary_version":"4.11.1+dfsg-1"},{"binary_name":"sleuthkit","binary_version":"4.11.1+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.0+dfsg-1","4.12.1+dfsg-1","4.12.1+dfsg-1.1ubuntu1","4.12.1+dfsg-1.1ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"libtsk19t64","binary_version":"4.12.1+dfsg-1.1ubuntu2"},{"binary_version":"4.12.1+dfsg-1.1ubuntu2","binary_name":"sleuthkit"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.1+dfsg-1.1ubuntu2","4.12.1+dfsg-3"],"ecosystem_specific":{"binaries":[{"binary_version":"4.12.1+dfsg-3","binary_name":"libtsk19t64"},{"binary_name":"sleuthkit","binary_version":"4.12.1+dfsg-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40026.json"}},{"package":{"name":"sleuthkit","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/sleuthkit?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.12.1+dfsg-3","4.12.1+dfsg-3build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libtsk19t64","binary_version":"4.12.1+dfsg-3build1"},{"binary_name":"sleuthkit","binary_version":"4.12.1+dfsg-3build1"}]},"database_specific":{"source":
