A very critical security vulnerability, identified as CVE-2026-98432, has been discovered in the Linux kernel... This use-after-free vulnerability in IPv4/TCP can affect systems remotely and without authentication! For Ubuntu, the priority is "High," and with a CVSS score of 9.8, it is classified as "Critical"! It appears a fix has not yet been released for Ubuntu, so those with servers need to monitor the situation closely. Don’t forget to update the kernel and reboot as soon as the patch is available; this is a serious issue for servers exposed to the internet...
