Doc Text:
A flaw was found in the AMD ROCm Communication Collectives Library (RCCL). Due to improper input validation, a network-adjacent attacker or a compromised peer node can supply a crafted memory address that the library accesses without proper verification. This vulnerability could allow an attacker to achieve arbitrary code execution on the host system.

Description OSIDB Bzimport 2026-10-06 20:22:29 UTC
Improper input validation in the AMD ROCm Communication Collectives Library (RCCL) could allow a compromised peer rank or network-adjacent attacker to dereference an attacker-controlled pointer, potentially resulting in remote code execution.
