CVE-2023-6270

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.28

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.

Recommendations For Linux kernel versions prior to 6.6.28, update to version 6.6.28 or later to resolve the issue. As a temporary workaround, consider disabling the aoecmd cfg pkts() function until a patch is available.
