Some contexts may not properly account for this scenario and leave request memory in an uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote code execution (RCE).","state":0,"publishedAt":"2026-10-21T13:48:34.845+00:00","modifiedAt":"2026-10-23T14:07:55.926+00:00","affected":[{"ecosystem":"Vendor product","name":"php-src","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"PHP Group\",\n                    \"product\": \"PHP\",\n                    \"packageName\": \"php-src\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"8.2.*\",\n                            \"lessThan\": \"8.2.35\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"8.3.*\",\n                            \"lessThan\": \"8.3.36\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"8.4.*\",\n                            \"lessThan\": \"8.4.27\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"8.5.*\",\n                            \"lessThan\": \"8.5.12\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":"CRITICAL"}],"references":["https://github.com/php/php-src/security/advisories/GHSA-w8hw-w9fx-j79w"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109618","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109618","identifiers":["CVE-2026-109618"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
