CVE-2025-39964: Linux kernel can mix data on cryptographic sockets
CVE-2025-39964 · published 2 days ago · actively exploited
Summary
The core Linux operating system code used by many distributions can accidentally combine data from different sources when two programs write to the same cryptographic socket at the same time. This can corrupt the data and cause the socket to behave incorrectly, potentially leading to crashes or security gaps. Install the latest kernel updates from your Linux vendor as soon as they are available to fix the problem.
