CVE-2023-6270: Kernel: aoe: improper reference count leads to use-after-free vulnerability

First published: Thu Jan 04 2024(Updated: )

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.
