Vulnerability from fkie_nvd - Published: 2017-12-30 01:29 - Updated: 2025-04-20 01:37
Severity ?
Summary
Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c in the Linux kernel through 4.14.10 allows attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure.

Esto se debe a que un kfree de la estructura de datos usbtv ocurre durante una llamada usbtv_video_free, pero el c\u00f3digo de la etiqueta usbtv_video_fail intenta acceder y liberar esta estructura de datos."
