[ Impact ]

A use-after-free vulnerability exists in the HiSilicon SEC2 crypto driver.
During packet transmission under heavy system load, the hardware may complete
processing a packet and free the request memory (req) before the transmission
function finishes. If the software subsequently accesses this freed req, a use-
after-free error occurs, which can lead to memory corruption or a system crash.

[ Fix ]

questing: clean cherry-pick

[ Test Plan ]

Boot tested.

[ Where Problems Could Occur ]

A regression in this fix would affect the HiSilicon SEC2 crypto accelerator
driver, potentially causing incorrect crypto operation results, request
handling errors, or instability on systems using this hardware for hardware-
accelerated cryptography.
