UBUNTU-CVE-2023-6270

A flaw was found in the ATA over Ethernet AoE driver in the Linux kernel. The aoecmdcfgpkts function improperly updates the refcnt on struct netdevice, 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...
