{"id":"DEBIAN-CVE-2026-14164","details":"A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.","modified":"2026-09-29T08:47:35.134140950Z","published":"2026-06-30T07:16:32.170Z","upstream":["CVE-2026-14164"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-14164"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Debian:12","purl":"pkg:deb/debian/libarchive?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.6.2-1+deb12u5"}]}],"versions":["3.6.2-1","3.6.2-1+deb12u1","3.6.2-1+deb12u2","3.6.2-1+deb12u3","3.6.2-1+deb12u4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-14164.json"}},{"package":{"name":"libarchive","ecosystem":"Debian:13","purl":"pkg:deb/debian/libarchive?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.4-4","3.7.4-4+deb13u1","3.8.4-1","3.8.5-1","3.8.6-1","3.8.7-1","3.8.8-1","3.8.8-2","3.8.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-14164.json"}},{"package":{"name":"libarchive","ecosystem":"Debian:14","purl":"pkg:deb/debian/libarchive?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.8-1"}]}],"versions":["3.7.4-4","3.8.4-1","3.8.5-1","3.8.6-1","3.8.7-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-14164.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
