Description
In the Linux kernel, the following vulnerability has been resolved:

ipmi:si: Return state to normal if message allocation fails

There were places where nothing would get started if a message
allocation failed, so the driver needs to return to normal state.

AI Analysis

Impact

In the Linux kernel, the IPMI monitor interface lacks proper error recovery when a message allocation fails, leaving the driver in an unusable state. This can stall IPMI operations and degrade system stability, effectively causing a denial of service. The weakness is a failure to handle resource allocation errors.

Affected Systems

All Linux kernel distributions that ship the default IPMI driver are affected; the issue is present in the kernel's IPMI silicon interface, regardless of vendor or distribution.

Risk and Exploitability

The CVSS score is not available publicly. EPSS is not provided and the vulnerability is not listed in CISA KEV. Exploitation requires a kernel‑space memory allocation failure, which is unlikely to be triggered remotely without elevated privileges. The risk is considered moderate; systems should address the defect promptly.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the Linux kernel to the latest stable release that incorporates the commits referenced in the advisory.
  • If an immediate kernel upgrade is not feasible, unload or disable the ipmi_si kernel module to stop IPMI activity until the patch is applied.
  • Restrict or block network traffic destined for the IPMI service, for example using firewall rules, to prevent management traffic from reaching the affected device during the mitigation period.
