USN-8197-1: Slurm vulnerability

Publication date

22 April 2026

Overview

Slurm could be made to send data to an arbitrary unix socket on the host.


Packages

  • slurm-llnl - Simple Linux Utility for Resource Management

Details

It was discovered that Slurm did not properly handle access control when
dealing with RPC traffic through PMI2 and PMIx, which could allow an
unprivileged user to send data to an arbitrary unix socket on the host.
An attacker could possibly use this issue to execute arbitrary code as
the root user.
