Vulnerability in the Linux Kernel Affecting TLS Implementation

CVE-2024-58240

What is CVE-2024-58240?

In the Linux kernel, a vulnerability was identified within the TLS implementation that involves handling of asynchronous decryption requests. The recent changes streamline the processing of non-asynchronous requests by eliminating unnecessary reference counting, thus simplifying the handling process. With appropriate synchronization mechanisms in place, the risk of potential race conditions—it was previously mitigated—has been reduced, making subsequent fixes more manageable. This vulnerability emphasizes the importance of efficient handling in encryption protocols within the kernel to enhance overall system security.
