{"id":"AZL-99726","summary":"CVE-2026-86145 affecting package pcre2 10.42-3","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":"2026-09-06T14:18:06.629088580Z","published":"2026-09-05T06:17:10Z","upstream":["CVE-2026-86145"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86145"}],"affected":[{"package":{"name":"pcre2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/pcre2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"10.42-3"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99726.json"}}],"schema_version":"1.9.0"}
