- CWE-416
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.
Affected configurations
• debian debian linux 10.0
• linux linux kernel (< 6.9)
• fedoraproject fedora 39
