Name of the Vulnerable Software and Affected Versions Linux Kernel versions prior to v4.19.194

Description The issue is related to a NULL pointer dereference in the llcp sock getname() function after a failed connect. This problem was introduced in version v3.3 and is fixed in Linux Kernel version v4.19.194. The actual impact and attack plausibility have not yet been proven.

Recommendations For Linux Kernel versions prior to v4.19.194, update to version v4.19.194 or later to resolve the issue. As a temporary workaround, consider restricting the use of the llcp sock getname() function until a patch is available.
