What is CVE-2026-49121?
CVE-2026-49121 is a critical unsafe deserialization vulnerability in ROCm aiter, published on 1 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
AI Tensor Engine for ROCm (AITER) through 0.1.14 contains an unauthenticated remote code execution vulnerability in the MessageQueue.recv() function within shm_broadcast.py that allows unauthenticated remote attackers to execute arbitrary code by sending a malicious pickle payload to a ZMQ SUB socket with no authentication, HMAC, or format validation. Attackers who can reach the writer XPUB endpoint on the cluster network or supply a forged Handle with an attacker-controlled remote_subscribe_addr can deliver a crafted pickle payload that executes arbitrary code simultaneously as the inference worker process on every remote reader worker.
Weakness: CWE-502
