What to do
AI-suggested
A patch has been applied to the Linux kernel to reorder the ICMP rate limiting checks and remove the global lock. Users should update their Linux kernel to a version including this fix once available. Since no fixed versions are explicitly stated in the provided data, check the vendor or Linux kernel advisories for the official fixed versions and apply updates accordingly.
Description
CVE-2024-47678 addresses a vulnerability in the Linux kernel's ICMP rate limiting mechanism. The order of applying rate limits was changed to check per-destination limits before host-wide limits to prevent side-channel attacks. The patch also removes a lock to optimize performance. The vulnerability has a medium severity with a CVSS score of 5.5 and does not have known exploits in the wild.
