NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-4_12_14-150100_197_114-default package and not the kernel-livepatch-4_12_14-150100_197_114-default package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call.
