Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - cancel work on re-enable SR-IOV timeout The QAT reset worker queues SR-IOV reenable work using a work_struct and completion embedded in an on-stack adf_sriov_dev_data. If the completion wait times out, the reset worker can return while device_sriov_wq still holds or executes the stack-backed work item. Cancel the work on the device_sriov_wq on timeout before the stack frame unwinds.
