TLS Vulnerability in Linux Kernel Affecting Data Transmission

CVE-2025-38471

What is CVE-2025-38471?

A vulnerability has been identified within the Linux kernel's TLS implementation, which could lead to use-after-free errors during data transmission. The issue arises when the queue is not accurately refreshed upon reading, resulting in the potential operation on outdated socket buffers (skbs). This flaw was exposed following recent enhancements to TCP that aggressively compact skbs. The incorrect handling of skbs can lead to a security risk, exposing systems to potential exploitation. It is critical for administrators to apply patches or updates addressing this issue to maintain a secure environment.
