Vulnerability from github – Published: 2024-01-04 18:30 – Updated: 2025-04-14 21:32

Details

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.

Severity

7.0 (High)
