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

net: usb: net1080: validate packet_len before pad-byte access in rx_fixup

For an even packet_len, net1080_rx_fixup() reads the pad byte at
skb->data[packet_len] before the skb->len != packet_len check further
down, and packet_len is only bounded against NC_MAX_PACKET. A malicious
NetChip 1080 device can send a short frame advertising a large even
packet_len (e.g. 0x4000), so the pad-byte read lands past the end of the
skb:

  BUG: KASAN: slab-out-of-bounds in net1080_rx_fixup
  Read of size 1 at addr ffff8880106c83c6 by task ksoftirqd/0/14

Reject the frame when packet_len >= skb->len before reading.
