Background
The crypto: sun8i-ss package is a component of the Linux Kernel that provides cryptographic services for the sun8i-ss hardware. It is responsible for handling encryption and decryption operations. The vulnerability in this package leads to a memory leak on the error path, potentially causing resource exhaustion and system instability.
Vulnerability Detail
The vulnerability in the crypto: sun8i-ss package occurs due to a memory leak on the error path. When certain error conditions are encountered during cryptographic operations, the package fails to release allocated memory, leading to a gradual depletion of system resources. An attacker could potentially exploit this vulnerability to exhaust system memory, causing denial-of-service conditions or other unpredictable behavior. The vulnerability was introduced in version v5.10 of the Linux Kernel and has been fixed in version v5.10.37.
