Detailsinfo

A vulnerability classified as critical was found in Linux Kernel (Operating System) (affected version not known). This vulnerability affects the function aoecmd_cfg_pkts of the component ATA over Ethernet Driver. The manipulation with an unknown input leads to a use after free vulnerability. The CWE definition for the vulnerability is CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was released 01/04/2024. The advisory is available at access.redhat.com. This vulnerability was named CVE-2023-6270 since 11/23/2023.
