Description OSIDB Bzimport 2026-09-17 18:14:44 UTC 
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.
