CVE-2025-38153

7.1 · HIGH
Published Jul 3, 2025 linux CWE-125 EPSS 0.17% (6th pctl)

Overview

CVE-2025-38153 is a high-severity vulnerability affecting linux linux_kernel. It was published on July 3, 2025 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, 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:

net: usb: aqc111: fix error handling of usbnet read calls

Syzkaller, courtesy of syzbot, identified an error (see report [1]) in

aqc111 driver, caused by incomplete sanitation of usb read calls'

results. This problem is quite similar to the one fixed in commit

920a9fa27e78 ("net: asix: add proper error handling of usb read errors").

For instance, usbnet_read_cmd() may read fewer than 'size' bytes,

even if the caller expected the full amount, and aqc111_read_cmd()

will not check its result properly. As [1] shows, this may lead

to MAC address in aqc111_bind() being only partly initialized,

triggering KMSAN warnings.

Fix the issue by verifying that the number of bytes read is

as expected and not less.

[1] Partial syzbot report:

BUG: KMSAN: uninit-value in is_valid_ether_addr include/linux/etherdevice.h:208 [inline]

BUG: KMSAN: uninit-value in usbnet_probe+0x2e57/0x4390 drivers/net/usb/usbnet.c:1830

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
