NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules package and not the kernel-zfcpdump-modules package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.
