Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.16-rc2. Affected is the function aoedev_downdev of the component aoe. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: aoe: clean device rq_list in aoedev_downdev() An aoe device's rq_list contains accepted block requests that are waiting to be transmitted to the aoe target. This queue was added as part of the conversion to blk_mq. However, the queue was not cleaned out when an aoe device is downed which caused blk_mq_freeze_queue() to sleep indefinitely waiting for those requests to complete, causing a hang. This fix cleans out the queue before calling blk_mq_freeze_queue().

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2025-38326 since 04/16/2025. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 264318 (Oracle Linux 7 / 8 : Unbreakable Enterprise kernel (ELSA-2025-20553)), which helps to determine the existence of the flaw in a target environment.
