{"id":"DEBIAN-CVE-2026-9149","details":"A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).","modified":"2026-09-02T08:47:33.385037218Z","published":"2026-05-21T00:16:35.630Z","upstream":["CVE-2026-9149"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-9149"}],"affected":[{"package":{"name":"libsolv","ecosystem":"Debian:12","purl":"pkg:deb/debian/libsolv?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.23-1","0.7.23-1+deb12u1","0.7.24-1","0.7.25-1","0.7.26-1","0.7.26-2","0.7.27-1","0.7.27-2","0.7.28-1","0.7.28-1.1~exp1","0.7.29-1","0.7.30-1","0.7.30-2","0.7.31-1","0.7.32-1","0.7.35-1","0.7.36-1","0.7.37-1","0.7.38-1","0.7.39-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-9149.json"}},{"package":{"name":"libsolv","ecosystem":"Debian:13","purl":"pkg:deb/debian/libsolv?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.7.32-1","0.7.35-1","0.7.36-1","0.7.37-1","0.7.38-1","0.7.39-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-9149.json"}},{"package":{"name":"libsolv","ecosystem":"Debian:14","purl":"pkg:deb/debian/libsolv?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.7.38-1"}]}],"versions":["0.7.32-1","0.7.35-1","0.7.36-1","0.7.37-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-9149.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
