CVE-2013-2094 Linux CVE debrief

CVE-2013-2094 is a Linux Kernel privilege escalation vulnerability that CISA lists in its Known Exploited Vulnerabilities catalog. Because it is on KEV, defenders should treat it as a high-priority patching item and follow vendor update guidance without delay. The supplied source record points to the upstream Linux kernel commit and the NVD entry, but does not provide affected version ranges or exploit details. CISA added the entry on 2022-09-15 and set a remediation due date of 2022-10-06.

Who should care

Linux administrators, kernel maintainers, cloud and container platform operators, and security teams responsible for patch compliance on systems running Linux kernels should pay attention. Any environment that depends on vendor-packaged or backported kernel updates should verify remediation status, especially where local privilege escalation would materially increase the impact of compromise.

Technical summary

The available source corpus identifies this as a Linux kernel privilege escalation issue and notes it in CISA’s KEV catalog. No additional technical specifics, impacted kernel versions, or exploitation mechanics are included in the supplied material. The official references available here are the CISA KEV catalog, the NVD record, the CVE record, and the kernel commit cited in the KEV notes.

Defensive priority

Urgent. Presence in CISA KEV indicates known exploitation risk and a need for prompt remediation. Prioritize patching and verification across all Linux systems that may carry the affected kernel line or a vendor backport of the fix.

Recommended defensive actions

  • Apply vendor-provided kernel updates and follow the vendor’s remediation instructions.
  • Confirm whether your distribution backported the fix rather than relying on upstream version numbers alone.
  • Inventory Linux systems, including servers, appliances, and container hosts, to verify kernel patch status.
  • Check for any systems that remain unpatched beyond the KEV due date of 2022-10-06 and escalate remediation.
  • Validate compliance against the NVD and CVE records, then document closure in patch management records.

Evidence notes

CISA’s KEV entry identifies the issue as “Linux Kernel Privilege Escalation Vulnerability,” marks it as a known exploited vulnerability, and states the required action: “Apply updates per vendor instructions.” The provided metadata lists dateAdded as 2022-09-15 and dueDate as 2022-10-06. The KEV notes also reference an upstream Linux kernel commit and the NVD detail page, but the supplied corpus does not include further technical breakdown or affected-version data.
