CVE-2026-92707 MessagePack: Nested arrays can blow past buffer length limits

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.303 and 3.1.9, deserializing attacker-controlled MessagePack data as System.Object through PrimitiveObjectFormatter can cause excessive memory allocation. The formatter allocates an object from each declared array length before the...
