A memory leak vulnerability in the Linux kernel's skb_segment_list function for GRO packets was resolved. This issue arose due to changes in socket memory accounting after a prior commit, causing improper handling of socket memory charges and resulting in a memory leak during packet forwarding. The vulnerability has a medium severity with a CVSS score of 5.5 and affects multiple Linux kernel versions prior to 6.8.0-1057.60~22.04.1 and related versions. A patch is available and included in updated Linux kernel packages distributed by Ubuntu. Users are advised to update and reboot to apply the fixes.
