Описание

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix memory leak when a wq is reset idxd_wq_disable_cleanup() which is called from the reset path for a workqueue, sets the wq type to NONE, which for other parts of the driver mean that the wq is empty (all its resources were released). Only set the wq type to NONE after its resources are released.

A flaw was found in the Linux kernel's dmaengine: idxd module. This vulnerability occurs when a workqueue is reset, specifically within the idxd_wq_disable_cleanup() function. The function prematurely sets the workqueue type to NONE before all associated resources are released, leading to a memory leak. This can potentially impact system stability and resource availability.
