Vulnerability from github – Published: 2026-09-17 18:32 – Updated: 2026-09-17 18:32

Details

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.
