CVE-2026-64577

CVE-2026-64577 concerns the Linux kernel GTP module. The vulnerability arises because gtp1u_send_echo_resp() ignores the return value of skb_pull_data(); the function’s caller guarantees 16 bytes but the pull may require 20, so an echo request of 16–19 bytes can fail to advance skb->data. This...
