NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-firmware package and not the kernel-firmware package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The networking implementation in the Linux kernel through 4.3.3, as used in Android and other products, does not validate protocol identifiers for certain protocol families, which allows local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application.
