What to do

  1. Check whether you run it. Look for Kernel in your asset inventory, including appliances and cloud images. Stack check lists every exploited Linux CVE at once.
  2. Apply the fix. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
  3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 19 Nov 2024.
  4. Get told next time. Email alerts when CISA adds a CVE for Linux.

Questions

Is CVE-2024-50302 being exploited?

Yes. CISA added CVE-2024-50302 to the Known Exploited Vulnerabilities catalog on 4 Mar 2025, which means there is reliable evidence of exploitation in the wild.

Is CVE-2024-50302 used in ransomware attacks?

CISA does not list known ransomware use for it. That can change, and exploitation alone is reason to fix it first.

How do I fix CVE-2024-50302?

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Check Linux's advisory for the fixed versions, and if you can't patch quickly, restrict access to the affected Kernel and watch it for signs of compromise.
