CVE-2024-38538

CVE-2024-38538 is a Linux kernel vulnerability in the bridge xmit path. The issue arises when a short skb (less than ETH_HLEN) is processed, risking uninitialized data in br_dev_xmit. The fix adds a guard to ensure the kernel only pulls the required ETH header bytes and does not assume availabili...
