{"id":"DEBIAN-CVE-2026-86145","details":"PCRE2 before 10.48 allows a pcre2_dfa_match out-of-bounds write because reuse of a cached workspace block, in a recursive DFA matching workspace, lacks a size check (even though a newly allocated block, for the same purpose, does have a size check). This outcome requires an attacker-controlled regular expression, or a recursive pattern in conjunction with a small heap limit (this can be set through the API).","modified":"2026-09-12T10:00:30.762968489Z","published":"2026-09-05T06:17:10.370Z","upstream":["CVE-2026-86145"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-86145"}],"affected":[{"package":{"name":"pcre2","ecosystem":"Debian:12","purl":"pkg:deb/debian/pcre2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.42-1+deb12u1"}]}],"versions":["10.42-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-86145.json"}},{"package":{"name":"pcre2","ecosystem":"Debian:13","purl":"pkg:deb/debian/pcre2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.46-1~deb13u2"}]}],"versions":["10.45-1","10.46-1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-86145.json"}},{"package":{"name":"pcre2","ecosystem":"Debian:14","purl":"pkg:deb/debian/pcre2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.48-1"}]}],"versions":["10.45-1","10.46-1","10.46-1~deb13u1","10.46-1~deb13u2","10.47-1","10.47-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-86145.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:H/A:L"}]}
