NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash.
