thunderbolt: Clamp XDomain response data copy to allocation size
Description

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Clamp XDomain response data copy to allocation size tb_xdp_properties_request() derives the per-packet copy length from the response header without checking that it fits in the previously allocated data buffer. A malicious peer can set its length field larger than the declared data_length, causing memcpy to write past the kcalloc allocation. Clamp the per-packet copy length so that the cumulative offset never exceeds data_len.

Solution
Clamp per-packet copy length to prevent buffer overflows.
  • Update the Linux kernel to include the fix.
  • Verify the per-packet copy length is clamped.
