CVE-2026-53146 Details
Description
In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Limit XDomain response copy to actual frame size tb_xdomain_copy() copies req->response_size bytes from the received packet buffer regardless of the actual frame size. When a short response arrives, this reads past the valid frame data in the DMA pool buffer into stale contents from previous transactions. Use the minimum of frame size and expected response size for the copy length.
A vulnerability in the Linux kernel's Thunderbolt driver allows for improper handling of XDomain response data. The issue arises because the 'tb_xdomain_copy' function copies a specified number of response bytes from the received packet buffer without considering the actual frame size. This can lead to reading beyond the valid data into stale contents from previous transactions, potentially causing data corruption or unexpected behavior. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the latest kernel version can be found on the official Linux kernel website.
