| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
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.Fix
