"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntap: add missing verification for short frame\n\nThe cited commit missed to check against the validity of the frame length\nin the tap_get_user_xdp() path, which could cause a corrupted skb to be\nsent downstack. Even before the skb is transmitted, the\ntap_get_user_xdp()-->skb_set_network_header() may assume the size is more\nthan ETH_HLEN. Once transmitted, this could either cause out-of-bound\naccess beyond the actual length, or confuse the underlayer with incorrect\nor inconsistent header length in the skb metadata.\n\nIn the alternative path, tap_get_user() already prohibits short frame which\nhas the length less than Ethernet header size from being transmitted.\n\nThis is to drop any frame shorter than the Ethernet header size just like\nhow tap_get_user() does.\n\nCVE: CVE-2024-41090"
