CVE-2023-6270

HIGH

Linux Kernel - Use-After-Free in ATA over Ethernet Driver

Title source: llm
STIX 2.1

Description

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.
