CVE-2023-54051

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

net: do not allow gso_size to be set to GSO_BY_FRAGS

One missing check in virtio_net_hdr_to_skb() allowed syzbot to crash kernels again [1]

Do not allow gso_size to be set to GSO_BY_FRAGS (0xffff), because this magic value is used by the kernel.
