Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there are no C++ wrappers.\r\n\r\nSecurity Fix(es):\n\nPCRE2 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).(CVE-2026-86145)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"pcre2","purl":"pkg:rpm/openEuler/pcre2&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.35-12.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["pcre2-10.35-12.oe2003sp4.aarch64.rpm","pcre2-debuginfo-10.35-12.oe2003sp4.aarch64.rpm","pcre2-debugsource-10.35-12.oe2003sp4.aarch64.rpm","pcre2-devel-10.35-12.oe2003sp4.aarch64.rpm"],"noarch":["pcre2-help-10.35-12.oe2003sp4.noarch.rpm"],"src":["pcre2-10.35-12.oe2003sp4.src.rpm"],"x86_64":["pcre2-10.35-12.oe2003sp4.x86_64.rpm","pcre2-debuginfo-10.35-12.oe2003sp4.x86_64.rpm","pcre2-debugsource-10.35-12.oe2003sp4.x86_64.rpm","pcre2-devel-10.35-12.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3814"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86145"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L"}],"database_specific":{"severity":"High"}}
