Background

The net/tls package is a component of the Linux Kernel, which provides Transport Layer Security (TLS) functionality for network communication. TLS is a cryptographic protocol that ensures secure communication over a network. The net/tls package in the Linux Kernel is responsible for handling TLS connections and providing encryption and decryption capabilities. This vulnerability affects the net/tls package in the Linux Kernel.

Vulnerability Detail

The vulnerability in the net/tls package is related to a flipped sign in the tls_err_abort() function calls. This flaw was introduced in version v4.17 of the Linux Kernel and fixed in version v5.10.77. The flipped sign can lead to unexpected behavior and potential security vulnerabilities. While the actual impact and attack plausibility have not been proven, it is important to address this vulnerability to ensure the integrity and security of TLS connections in the Linux Kernel.
