Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.19.7

Description The issue is related to a use-after-free in the ALSA driver. A local user could exploit this by supplying a malicious USB Sound device that is mishandled in the usb audio probe function in sound/usb/card.c. This could allow an attacker to execute arbitrary code or cause a denial of service.

Recommendations For Linux kernel versions prior to 4.19.7, consider updating to version 4.19.7 or later to resolve the issue. As a temporary workaround, consider restricting the use of USB Sound devices to minimize the risk of exploitation.
