How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf-debuginfo package and not the perf-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on struct net_device, and a use-after-free can be triggered by racing between the free on the struct and the access through the skbtxq global queue. This could lead to a denial of service condition or potential code execution.
