JSON

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.
