Before util-linux 2.41.4, `parse_dos_extended()` in `libblkid/src/partitions/dos.c` computes an extended-partition start sector with 32-bit addition and does not apply the extended-area bounds checks to the first two EBR entries. A local attacker who causes a crafted DOS extended-partition disk image or removable medium to be probed can wrap `cur_start + start` to sector zero and cause libblkid to report a false partition overlapping the MBR. This directly compromises the integrity of the reported partition metadata; disk modification or availability loss requires a separate downstream consumer to act on that metadata. This issue is fixed in 2.41.4."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"util-linux","product":"util-linux","versions":[{"version":"< 2.41.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H","baseScore":8.0,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.5,"impactScore":5.5}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-14T16:11:25.315520Z","id":"CVE-2026-53615","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-190"}]}],"references":[{"url":"https://github.com/util-linux/util-linux/commit/05c2dbadf34cc74192287f377904afaaf4061623","source":"security-advisories@github.com"},{"url":"https://github.com/util-linux/util-linux/commit/a2d858176b609ab5b8535021a3af9cd302d23d31","source":"security-advisories@github.com"},{"url":"https://github.com/util-linux/util-linux/commit/e9d544d013267ea86b70ee8ff78abd280e6641af","source":"security-advisories@github.com"},{"url":"https://github.com/util-linux/util-linux/releases/tag/v2.41.4","source":"security-advisories@github.com"},{"url":"https://github.com/util-linux/util-linux/security/advisories/GHSA-h4rw-gv36-wmp5","source":"security-advisories@github.com"}]}}]}
