CVE-2025-40172

7.8 · HIGH
Published Nov 12, 2025 EPSS 0.14% (4th pctl)

Overview

CVE-2025-40172 is a high-severity vulnerability. It was published on November 12, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

accel/qaic: Treat remaining == 0 as error in find_and_map_user_pages()

Currently, if find_and_map_user_pages() takes a DMA xfer request from the

user with a length field set to 0, or in a rare case, the host receives

QAIC_TRANS_DMA_XFER_CONT from the device where resources->xferred_dma_size

is equal to the requested transaction size, the function will return 0

before allocating an sgt or setting the fields of the dma_xfer struct.

In that case, encode_addr_size_pairs() will try to access the sgt which

will lead to a general protection fault.

Return an EINVAL in case the user provides a zero-sized ALP, or the device

requests continuation after all of the bytes have been transferred.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
