About this tag
The tcp metrics tag on WindowsForum.com covers discussions about TCP metrics, including hardening and security patches. One recent thread details a Linux kernel fix for CVE-2025-40075, which addresses a synchronization gap in the TCP metrics code by replacing direct dst_dev reads with an RCU-aware helper. This change prevents crashes and memory-safety hazards in concurrent scenarios. The tag is relevant for administrators and kernel integrators interested in TCP metrics stability and security.
