Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> thunderbolt: Limit XDomain response copy to actual frame size<br /> <br /> tb_xdomain_copy() copies req-&gt;response_size bytes from the received<br /> packet buffer regardless of the actual frame size. When a short<br /> response arrives, this reads past the valid frame data in the DMA<br /> pool buffer into stale contents from previous transactions.<br /> <br /> Use the minimum of frame size and expected response size for the<br /> copy length.
