Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
