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

net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup

ax88179rxfixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular:

  • The metadata array (hdroff..hdroff+2*pkt_cnt) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips.
  • A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack.
  • A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data.

I have tested that this can be used by a malicious USB device to send a bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response that contains random kernel heap data. It's probably also possible to get OOB writes from this on a little-endian system somehow - maybe by triggering skb_cow() via IP options processing -, but I haven't tested that.
