kernel: net: add more sanity checks to qdisc_pkt_len_init()

A flaw was found in the Linux kernel's network handling, specifically within the qdiscpktleninit function. A local user could exploit this by crafting a malicious Generic Segmentation Offload GSO packet. Insufficient sanity checks in the virtionethdrtoskb function allow for an underflow in the...
