- 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 cJSONUtilsApplyPatches() or cJSONUtilsApplyPatchesCaseSensitive(). A patch containing add and copy operations grafts duplicated subtrees to amplify document depth beyond the parser's nesting limit: cJSONDelete() recurses with no depth bound, and the cJSONDuplicate() guard CJSONCIRCULARLIMIT 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.
