A heap overflow bug was recently discovered in the Linux kernel. The patch is available now in most major Linux distributions.

Way back in August Intel posted a set of Linux kernel patches for supporting "unaccepted memory" by the Linux kernel in preparation for next-generation Xeon processors and speeding up the boot time for guest virtual machines making use of Intel's Trust Domain Extensions (TDX) security feature. Unaccepted memory support hasn't yet made it to the mainline kernel but now a second iteration of the patches have been posted.

Recent years have demonstrated that Windows users are not the only ones who should be concerned about malware. Linux is becoming an increasingly popular target among malware operators due to the growing popularity of the open-source OS and the high-value devices it powers worldwide. Security researchers from AT&T Alien Labs are now warning that ''cyber gangs have started infecting Linux machines via a fileless malware installation technique that until recently was more commonly used against Windows-based systems''.

The Linux Vendor Firmware Service (LVFS) that integrates with Fwupd for delivering firmware updates primarily to Linux users is surging with around three times the normal traffic volume. Unfortunately, this boost in traffic appears to be due to vendor(s) releasing new system firmware updates ahead of disclosing a presumptive security issue.

The new year has brought some bad news for Linux users and enthusiasts. Research reveals that Linux-specific malware saw a 35% increase in 2021 compared to a year before.

Welcome to LinuxSecurity.com - the community's central source for information on Linux and open source security since 1996.

Lots of people ''run Linux'' without really knowing or caring '' many home routers, navigational aids, webcams and other IoT devices are based on it; the majority of the world's mobile phones run a Linux-derived variant called Android; and many, if not most, of the ready-to-go cloud services out there rely on Linux to host your content.

Tech giants and federal agencies meet at the White House to discuss open-source software security, a response to the widespread Log4j vulnerability that's worrying industry and cyber leaders.

This document takes you through the basics of intrusion detection, the steps necessary to configure a host to run the snort network intrusion detection system, testing its operation, and alerting you to possible intrusion events.

Regardless of the Linux distribution you're using, staying on top of the latest security advisories is essential in maintaining an updated, secure Linux system.

Security is a process, not a product. We're going to be cleaning up Apache Log4j security problems for months to come, but the real problem isn't that it was open-source software. It's how we track and use open-source code.

Linux Mint has released version 20.3, codenamed 'Una,' as a long-term support version that will receive security updates until 2025. Learn what's new in this release and how to upgrade.

The tech industry is readying solutions to the security risks posed by the collaborative software that underpins modern-day computing '' but aid from Washington could be essential to the project's success.

With the support of the open-source community behind it and a strict privilege system embedded in its architecture, Linux has security built into its design. That being said, gone are the days that Linux system administrators could get away with subpar security practices. Cyber criminals have come to view Linux as a viable attack target due to its growing popularity, the valuable devices it powers worldwide, and an array of dangerous new Linux malware variants that have emerged in recent years.
