Furthermore if multi-buffer would come to play then skb_shared_info stored at the end of XSK frame would be corrupted.</p> <p>HW typically works with 128-aligned sizes so let us provide this value as bare minimum.</p> <p>Multi-buffer setting is known later in the configuration process so besides accounting for 128 bytes, let us also take care of tailroom space upfront.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>xsk: tighten UMEM headroom validation to account for tailroom and min frame</p> <p>The current headroom validation in xdp_umem_reg() could leave us with insufficient space dedicated to even receive minimum-sized ethernet frame.
