{"id":"DEBIAN-CVE-2026-48864","details":"A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.","modified":"2026-09-18T09:00:23.365388652Z","published":"2026-05-26T17:16:54.050Z","upstream":["CVE-2026-48864"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-48864"}],"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","0.7.39-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48864.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","0.7.39-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48864.json"}},{"package":{"name":"libsolv","ecosystem":"Debian:14","purl":"pkg:deb/debian/libsolv?arch=source&distro=forky"},"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","0.7.39-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-48864.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
