Description

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