AV:L/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.9

Description The issue is related to a driver error in the Linux kernel, specifically in the drivers/net/wireless/ath/ath6kl/usb.c file, which is associated with NULL pointer dereference errors. This can be exploited by an attacker to cause a denial of service. The error occurs due to an incomplete address in an endpoint descriptor.

Recommendations For Linux kernel versions prior to 5.2.9, update to version 5.2.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable driver to minimize the risk of exploitation.
