slurm

An issue was discovered in SchedMD Slurm 22.05.x, 23.02.x, and 23.11.x. Because of a double free, attackers can cause a denial of service or possibly execute arbitrary code. The fixed versions are 22.05.11, 23.02.7, and 23.11.1.

CVE-2023-49937 is a security vulnerability identified in the SchedMD Slurm workload manager versions 22.05.x, 23.02.x, and 23.11.x. The root cause is a double free bug, a memory management error where the same memory is freed more than once. This can lead to undefined behavior, including memory corruption, which attackers can leverage to cause a denial of service (DoS) by crashing the Slurm service or, more critically, to execute arbitrary code on the affected system. Slurm is a widely adopted open-source job scheduler used primarily in high-performance computing (HPC) clusters to allocate resources and manage workloads. The vulnerability's exploitation could allow attackers to disrupt HPC operations or gain unauthorized control over cluster nodes. The fixed versions—22.05.11, 23.02.7, and 23.11.1—address this double free issue. No public exploits or active attacks have been reported yet, but the nature of the flaw means that once exploit code is developed, the impact could be severe. Exploitation likely requires some level of access to the Slurm environment, but no user interaction is needed once access is obtained. The vulnerability does not have an assigned CVSS score, but its potential for arbitrary code execution and service disruption makes it a significant threat to HPC environments relying on affected Slurm versions.

CVE-2023-49937: n/a

An issue was discovered in SchedMD Slurm 22.05.x, 23.02.x, and 23.11.x. A NULL pointer dereference leads to denial of service. The fixed versions are 22.05.11, 23.02.7, and 23.11.1.

CVE-2023-49936 is a vulnerability identified in the Slurm workload manager developed by SchedMD, affecting versions 22.05.x, 23.02.x, and 23.11.x. The flaw arises from a NULL pointer dereference condition that can be triggered to cause a denial-of-service (DoS) state, effectively crashing the Slurm daemon or causing it to become unresponsive. Slurm is widely used in high-performance computing (HPC) environments to schedule and manage compute jobs across clusters. A NULL pointer dereference typically occurs when the software attempts to access or manipulate memory through a pointer that has not been properly initialized or has been set to NULL, leading to a segmentation fault or crash. This vulnerability does not require authentication or user interaction, making it easier for an attacker with network access to the Slurm controller or compute nodes to exploit. The impact is primarily availability-related, as the disruption of Slurm services can halt job scheduling and cluster operations, potentially delaying scientific computations or business-critical workloads. The vendor has released patched versions 22.05.11, 23.02.7, and 23.11.1 to address this issue. There are no reports of active exploitation in the wild at this time, but the presence of a straightforward DoS vector in a critical HPC component warrants prompt attention.
