{"id":"AZL-94410","summary":"CVE-2026-67215 affecting package apparmor 3.1.7-1","details":"cJSON through 1.7.19 is vulnerable to uncontrolled recursion leading to stack exhaustion when an untrusted RFC 6902 JSON Patch is applied via cJSONUtils_ApplyPatches() or cJSONUtils_ApplyPatchesCaseSensitive(). A patch containing add and copy operations grafts duplicated subtrees to amplify document depth beyond the parser's nesting limit: cJSON_Delete() recurses with no depth bound, and the cJSON_Duplicate() guard CJSON_CIRCULAR_LIMIT is set to 10000, ten times the parser's 1000-level nesting limit and high enough to overflow a default thread stack. An attacker who can supply the patch document can crash the process, resulting in denial of service.","modified":"2026-08-31T05:26:27Z","published":"2026-07-29T14:16:35Z","upstream":["CVE-2026-67215"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67215"}],"affected":[{"package":{"name":"apparmor","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/apparmor"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.1.7-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-94410.json"}}],"schema_version":"1.9.0"}
