Background
The crypto: hisilicon/sec package is a component of the Linux Kernel, which is responsible for providing cryptographic functionality. It includes various algorithms and protocols for secure communication and data protection. The hisilicon/sec module specifically handles cryptographic operations for HiSilicon SoCs. This vulnerability affects the aead software fallback mechanism within the engine, potentially leading to security issues.
Vulnerability Detail
The vulnerability in the crypto: hisilicon/sec package arises from a flaw in the aead software fallback for the engine. When the hardware acceleration engine encounters an error during cryptographic operations, it falls back to software-based processing. However, due to a coding error, this fallback mechanism can be exploited by an attacker to bypass security measures or cause unexpected behavior. The impact of this vulnerability could range from information disclosure to privilege escalation, depending on the specific usage scenario.
