FKIE_CVE-2025-38153

Vulnerability from fkie_nvd - Published: 2025-07-03 09:15 - Updated: 2026-06-17 09:16
Severity
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Summary
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.

Syzkaller, cortes\u00eda de syzbot, identific\u00f3 un error (v\u00e9ase el informe [1]) en el controlador aqc111, causado por una correcci\u00f3n incompleta de los resultados de las llamadas de lectura USB. Este problema es bastante similar al corregido en el commit 920a9fa27e78 (\"net: asix: a\u00f1adir un manejo adecuado de errores de lectura USB\"). Por ejemplo, usbnet_read_cmd() puede leer menos bytes que \u0027size\u0027, incluso si el emisor esperaba la cantidad completa, y aqc111_read_cmd() no comprobar\u00e1 su resultado correctamente. Como se muestra en [1], esto puede provocar que la direcci\u00f3n MAC en aqc111_bind() se inicialice solo parcialmente, lo que activa advertencias KMSAN. Solucione el problema verificando que el n\u00famero de bytes le\u00eddos sea el esperado y no menor.
