Description

A flaw was found in the Linux kernel's hisilicon/sec2 cryptographic module. Under heavy system load during packet transmission, the hardware may free request memory before the software completes its processing. This can lead to a use-after-free error when the software attempts to access the freed memory, potentially resulting in system instability or a denial of service.

No mitigation is specified in collected source.
