Apr 25, 2024
CVE-2022-2588 is a notable vulnerability affecting the Linux kernel, with a severity rating of 7.8 HIGH by NIST and 5.3 MEDIUM by Canonical Ltd. This issue occurs in the cls_route filter implementation, where an old filter is not removed from the hashtable before being freed if its handle has the value 0. The vulnerability impacts various systems running the Linux kernel up to version 5.19.17, including several versions of Canonical's Ubuntu Linux.
How do I know if I'm affected?
If you're wondering whether you're affected by the vulnerability, you'll need to check if your system is running the Linux kernel up to version 5.19.17 or any of these Ubuntu Linux versions: 14.04, 16.04, 18.04, 20.04, and 22.04. The vulnerability is related to the cls_route filter implementation in the Linux kernel, which doesn't remove an old filter from the hashtable before freeing it if its handle has the value 0. Keep in mind that this information is for informational purposes only and doesn't provide a solution to fix the problem.
What should I do if I'm affected?
If you're affected by the vulnerability, it's crucial to update your system. For Linux kernel users, upgrade to version 5.19 or later. Ubuntu users should follow the update instructions provided by Canonical and reboot their computer to apply the changes. Stay vigilant and keep your system up-to-date to minimize risks.
Is CVE-2022-2588 in CISA’s Known Exploited Vulnerabilities Catalog?
As of now, CVE-2022-2588 is not listed in CISA's Known Exploited Vulnerabilities Catalog. This vulnerability, found in the Linux kernel's cls_route filter implementation, could potentially allow a local attacker to cause a denial of service or execute arbitrary code. It was added to the National Vulnerability Database on January 8, 2024. There is no specific due date or required action mentioned, but updating your system to a patched version is highly recommended.
Weakness enumeration
The Weakness Enumeration for CVE-2022-2588 includes two main issues: Double Free (CWE-415) and Use After Free (CWE-416). This vulnerability affects the cls_route filter implementation in the Linux kernel, potentially causing system crashes or arbitrary code execution.
For more details
CVE-2022-2588 is a significant vulnerability affecting the Linux kernel and various Ubuntu Linux versions. To learn more about its description, severity, technical details, and known affected software configurations, refer to the NVD page or the resources listed below.
