In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/sec2 - prevent req used-after-free for sec
During packet transmission, if the system is under heavy load,
the hardware might complete processing the packet and free the
request memory (req) before the transmission function finishes.
If the software subsequently accesses this req, a use-after-free
error will occur. The qp_ctx memory exists throughout the packet
sending process, so replace the req with the qp_ctx.
