{"id":"AZL-86369","summary":"CVE-2026-41257 affecting package jq for versions less than 1.7.1-6","details":"jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB (via deeply nested generator forks), the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for a memmove with attacker-influenced offsets.","modified":"2026-08-31T05:26:27Z","published":"2026-05-11T18:16:34Z","upstream":["CVE-2026-41257"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41257"}],"affected":[{"package":{"name":"jq","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/jq"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.1-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86369.json"}}],"schema_version":"1.9.0"}
