Description
A vulnerability in the Linux kernel's crypto QAT driver involving the handling of SR-IOV re-enable work has been resolved. The issue occurs when the QAT reset worker queues SR-IOV re-enable work using a work_struct and completion embedded in an on-stack structure. If the completion wait times out, the reset worker may return while the work item is still held or executing, potentially leading to use-after-return conditions. The fix cancels the work on timeout before the stack frame unwinds.
