CVE-2026-31441 Details
Description
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 memory leak vulnerability has been identified in the Linux kernel's DMA engine, specifically within the Intel Integrated Accelerator (IDX) driver. This issue arises when a workqueue is reset, as the cleanup process improperly manages the workqueue's resource state. The vulnerability is present in the Linux kernel stable tree.
Users can apply the latest patches available in the Linux kernel stable repository to address this vulnerability.
