{"id":"AZL-86361","summary":"CVE-2026-7568 affecting package php for versions less than 8.3.31-1","details":"In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the metaphone() function in ext/standard/metaphone.c uses a signed int variable to track the current position within the input string. If a string longer than 2,147,483,647 bytes is passed, a signed integer overflow occurs, resulting in undefined behavior. This can lead to an out-of-bounds read, causing a segmentation fault or access to unrelated memory, and may affect the availability of the PHP process.","modified":"2026-09-03T05:27:10Z","published":"2026-05-10T05:16:11Z","upstream":["CVE-2026-7568"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7568"}],"affected":[{"package":{"name":"php","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/php"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.31-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86361.json"}}],"schema_version":"1.9.0"}
