Linux Security Features

It starts as an innocuous bug. A developer miscalculates an offset, a boundary check is missing, a buffer is too small”just a simple oversight in code. But in the world of software security , even the smallest mistakes can rip holes in your defenses. Enter the out-of-bounds write Linux security vulnerability: a coding flaw with the potential to destabilize systems, corrupt data, or worse, create a direct path for attackers to execute malicious code. If you’re managing Linux systems”whether in production, testing, or anywhere in between”this is the kind of vulnerability you don’t ignore.

CVE-2025-11371 doesn’t target Linux directly. It doesn’t need to.

The Extended Berkeley Packet Filter (eBPF) was created to make Linux more observable and secure. It extends kernel functionality without requiring new modules or recompilation, enabling precise monitoring, tracing, and policy enforcement at runtime. For defenders, it promised transparency. For attackers, it opened a new space to hide.

For Linux users, software supply chain security means protecting the entire path from source to install. It covers who authors and reviews the code, how it is built, how artifacts and metadata are signed, where they are mirrored, and which keys the client trusts. In short: provenance, freshness, and scoped trust across the package pipeline.
