CVE-2026-115912: Python Shared Memory Deserialization Unauthenticated Handlecve-2026-115912-python-shared-memory-deserialization-unauthenticated-handle
Bytes read from shared memory at an externally supplied handle (address/monotonic_id) are passed to deserialization without verifying an authenticated signature for the handle. A caller who controls the handle can point the reader at attacker-chosen bytes inside the shared segment; those bytes reach deserialize()/pickle.loads() and give arbitrary Python code
