## Technical details

An attacker-controlled heap-based buffer overflow exists in the slurmstepd process when running with root permissions. The vulnerability requires attacker control over input to trigger the overflow, potentially through job submission or task execution mechanisms. Successful exploitation grants arbitrary code execution at the root privilege level.
