Stay Ahead With Linux Security Features

Ai And Patching Hero Esm H350
Price Tag%201security advisory vulnerability

For decades, Linux defenders relied on a comfortable assumption: a public security patch did not imply an imminent vulnerability. While open-source openness made vulnerability fixes public to everyone on kernel.org or the Linux Kernel Mailing List (LKML), converting a raw commit into a weaponized exploit took a significant amount of manual effort. This delay, estimated in weeks or months, gave businesses enough time to assess exposure, organize testing windows, and push changes across...

Trust Kubernetes Not Enough Hero Esm H350
Price Tag%201security advisory path traversal

Two newly fixed storage bugs in Kubernetes showed more than just a problem with path traversal. They found a common security flaw in the cloud: powerful parts often think that requests accepted by a higher system are safe to run. This is a simple lesson for the platform and security teams: RBAC can accept a request without showing that its parameters will stay within a certain filesystem boundary. This is clear from a new study from SentinelLabs into flaws in the Kubernetes CSI drivers for NFS...

Linux Security Roundup July 23 2026 Esm H350
Price Tag%201security advisory update

A large volume of Linux security updates and advisories this week across major distributions once again, but it wasn't just the volume that was the story. Where maintainers and security teams focused their attention was evident in the concentration of fixes targeting Linux kernel updates, identity services, DNS infrastructure, and internet-facing software. . Instead of looking at each advisory in isolation, administrators gain more value from the general trends they reveal about Linux security...

Linux IAM Misconfiguration Hero Esm H350
Price Tag%201identity management security tactics

For years, we secured our Linux infrastructure by building walls: VPCs, security groups, and hardened SSH configurations. We treated the cloud like a virtual data center, assuming that if we kept the "bad guys" out of the network, our workloads were safe. . That model is no longer sufficient. Today, one of the most common paths from an initial compromise to a major cloud breach is the identity assigned to your Linux workload. When an attacker gains code execution on a Linux instance—through a...

Linux Vuln Hero Esm H350
Price Tag%201security practices patch management

Most of us don't hear about a kernel vulnerability until a CVE lands in our inbox or the vulnerability scanner starts complaining. By then, the patch isn't new anymore. Kernel developers may have been passing it around for review, arguing over the implementation, or revising it for days before anyone outside that community noticed it. None of those discussions are secret. They're sitting in mailing list archives, Git commits, and patch reviews where they've been the whole time. The strange...
