FKIE_CVE-2024-41038

Vulnerability from fkie_nvd - Published: 2024-07-29 15:15 - Updated: 2026-06-17 07:47
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers Check that all fields of a V2 algorithm header fit into the available firmware data buffer. The wmfw V2 format introduced variable-length strings in the algorithm block header. This means the overall header length is variable, and the position of most fields varies depending on the length of the string fields. Each field must be checked to ensure that it does not overflow the firmware data buffer. As this ia bugfix patch, the fixes avoid making any significant change to the existing code. This makes it easier to review and less likely to introduce new bugs.

Verifique que todos los campos de un encabezado de algoritmo V2 encajen en el b\u00fafer de datos del firmware disponible. El formato wmfw V2 introdujo cadenas de longitud variable en el encabezado del bloque del algoritmo. Esto significa que la longitud total del encabezado es variable y la posici\u00f3n de la mayor\u00eda de los campos var\u00eda seg\u00fan la longitud de los campos de cadena. Se debe verificar cada campo para garantizar que no desborde el b\u00fafer de datos del firmware. Como se trata de un parche de correcci\u00f3n de errores, las correcciones evitan realizar cambios significativos en el c\u00f3digo existente. Esto hace que sea m\u00e1s f\u00e1cil de revisar y menos probable que se introduzcan nuevos errores."
