Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iommu: Fix potential memory leak in iopf_queue_remove_device()<br /> <br /> The iopf_queue_remove_device() helper removes a device from the per-iommu<br /> iopf queue when PRI is disabled on the device. It responds to all<br /> outstanding iopf&amp;#39;s with an IOMMU_PAGE_RESP_INVALID code and detaches the<br /> device from the queue.<br /> <br /> However, it fails to release the group structure that represents a group<br /> of iopf&amp;#39;s awaiting for a response after responding to the hardware. This<br /> can cause a memory leak if iopf_queue_remove_device() is called with<br /> pending iopf&amp;#39;s.<br /> <br /> Fix it by calling iopf_free_group() after the iopf group is responded.
