CVE-2026-93162 PUBLISHED

crypto: qat - cancel work on re-enable SR-IOV timeout

Assigner: Linux
Reserved: 17.09.2026 Published: 17.09.2026 Updated: 17.09.2026

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.
