Title
crypto: hisilicon/sec2 - prevent req used-after-free for sec
Summary
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.
Severity
No CVSS data available.
