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 has a pcre2_match out-of-bounds read after a JIT fallback when an attacker can provide invalid UTF data.(CVE-2026-89156)\n\nPCRE2 before 10.48, on 32-bit platforms, has a pcre2_pattern_convert out-of-bounds write when an attacker can provide a large pattern.(CVE-2026-89157)\n\nPCRE2 before 10.48, on 32-bit platforms, has a pcre2_compile_32 integer overflow and resultant out-of-bounds write.(CVE-2026-89158)\n\nPCRE2 before 10.48 has a pcre2_match out-of-bounds read during the PCRE2_MATCH_INVALID_UTF matching of an invalid UTF subject.(CVE-2026-89160)\n\nIn PCRE2 before 10.48, pcre2_jit_match mishandles a previously copied subject being passed in as a context. An incorrect free operation can occur.(CVE-2026-89161)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP4","name":"pcre2","purl":"pkg:rpm/openEuler/pcre2&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.42-20.oe2403sp4"}]}],"ecosystem_specific":{"aarch64":["pcre2-10.42-20.oe2403sp4.aarch64.rpm","pcre2-debuginfo-10.42-20.oe2403sp4.aarch64.rpm","pcre2-debugsource-10.42-20.oe2403sp4.aarch64.rpm","pcre2-devel-10.42-20.oe2403sp4.aarch64.rpm"],"noarch":["pcre2-help-10.42-20.oe2403sp4.noarch.rpm"],"src":["pcre2-10.42-20.oe2403sp4.src.rpm"],"x86_64":["pcre2-10.42-20.oe2403sp4.x86_64.rpm","pcre2-debuginfo-10.42-20.oe2403sp4.x86_64.rpm","pcre2-debugsource-10.42-20.oe2403sp4.x86_64.rpm","pcre2-devel-10.42-20.oe2403sp4.x86_64.rpm"]}},{"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":"10.35-17.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["pcre2-10.35-17.oe2003sp4.aarch64.rpm","pcre2-debuginfo-10.35-17.oe2003sp4.aarch64.rpm","pcre2-debugsource-10.35-17.oe2003sp4.aarch64.rpm","pcre2-devel-10.35-17.oe2003sp4.aarch64.rpm"],"noarch":["pcre2-help-10.35-17.oe2003sp4.noarch.rpm"],"src":["pcre2-10.35-17.oe2003sp4.src.rpm"],"x86_64":["pcre2-10.35-17.oe2003sp4.x86_64.rpm","pcre2-debuginfo-10.35-17.oe2003sp4.x86_64.rpm","pcre2-debugsource-10.35-17.oe2003sp4.x86_64.rpm","pcre2-devel-10.35-17.oe2003sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"pcre2","purl":"pkg:rpm/openEuler/pcre2&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.39-24.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["pcre2-10.39-24.oe2203sp4.aarch64.rpm","pcre2-debuginfo-10.39-24.oe2203sp4.aarch64.rpm","pcre2-debugsource-10.39-24.oe2203sp4.aarch64.rpm","pcre2-devel-10.39-24.oe2203sp4.aarch64.rpm"],"noarch":["pcre2-help-10.39-24.oe2203sp4.noarch.rpm"],"src":["pcre2-10.39-24.oe2203sp4.src.rpm"],"x86_64":["pcre2-10.39-24.oe2203sp4.x86_64.rpm","pcre2-debuginfo-10.39-24.oe2203sp4.x86_64.rpm","pcre2-debugsource-10.39-24.oe2203sp4.x86_64.rpm","pcre2-devel-10.39-24.oe2203sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"pcre2","purl":"pkg:rpm/openEuler/pcre2&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.42-20.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["pcre2-10.42-20.oe2403sp1.aarch64.rpm","pcre2-debuginfo-10.42-20.oe2403sp1.aarch64.rpm","pcre2-debugsource-10.42-20.oe2403sp1.aarch64.rpm","pcre2-devel-10.42-20.oe2403sp1.aarch64.rpm"],"noarch":["pcre2-help-10.42-20.oe2403sp1.noarch.rpm"],"src":["pcre2-10.42-20.oe2403sp1.src.rpm"],"x86_64":["pcre2-10.42-20.oe2403sp1.x86_64.rpm","pcre2-debuginfo-10.42-20.oe2403sp1.x86_64.rpm","pcre2-debugsource-10.42-20.oe2403sp1.x86_64.rpm","pcre2-devel-10.42-20.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"pcre2","purl":"pkg:rpm/openEuler/pcre2&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.42-20.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["pcre2-10.42-20.oe2403sp3.aarch64.rpm","pcre2-debuginfo-10.42-20.oe2403sp3.aarch64.rpm","pcre2-debugsource-10.42-20.oe2403sp3.aarch64.rpm","pcre2-devel-10.42-20.oe2403sp3.aarch64.rpm"],"noarch":["pcre2-help-10.42-20.oe2403sp3.noarch.rpm"],"src":["pcre2-10.42-20.oe2403sp3.src.rpm"],"x86_64":["pcre2-10.42-20.oe2403sp3.x86_64.rpm","pcre2-debuginfo-10.42-20.oe2403sp3.x86_64.rpm","pcre2-debugsource-10.42-20.oe2403sp3.x86_64.rpm","pcre2-devel-10.42-20.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4111"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89156"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89157"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89158"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89160"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89161"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}],"database_specific":{"severity":"High"}}
