V8 Zero Day Chrome Esm H350
Security Vulnerabilities Price Tag 1security advisory zero-day

CISA added CVE-2026-11645 to its Known Exploited Vulnerabilities catalog after Google confirmed active exploitation of the flaw. The bug sits in V8, the JavaScript engine behind Chrome and Chromium. . That's where this gets more interesting. Most coverage will focus on Chrome because that's where the patch landed. But the affected component is V8. Chromium relies on it. Electron relies on it. Plenty of desktop software Linux users interact with every day relies on it too, often without much...

For years, IPv4 was the only proxy type that really mattered for anyone running automation off a Linux box. IPv6 was the protocol everyone said they’d migrate to, but almost nobody actually did. In 2026, that’s finally starting to shift. . The problem is that most admins stick with IPv4 out of habit. They know it; it’s what their tooling defaults to, and they don’t see a reason to change. Some are overpaying for addresses they don’t need. Others would quietly break their scrapers, scripts, or...

Researchers recently identified another wave of malicious packages on PyPI linked to the broader Mini Shai-Hulud campaign, a worm-like supply chain attack that spread through trusted software packages. On the surface, the packages looked no different from thousands of others published to the repository each week. . Instead of trying to break into a target network directly, the attackers hid malicious code inside software that developers were already using. A few downloads are all it takes....

IronWorm steals credentials and uses them to spread beyond the original victim, turning developer access into a supply chain risk. . A new campaign targeting npm has evolved past simple credential theft. Researchers identified IronWorm, a self-spreading threat. It harvests high-value Linux development secrets—SSH keys, cloud tokens, package publishing credentials. One compromised workstation becomes a launchpad for downstream supply chain attacks. This is not a get-in-and-get-out operation....

The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Fedora 38: Enhanced Compiler Security With _FORTIFY_SOURCE=3

In addition to Fedora 38 now allowing "no-omit-frame-pointer" to enhance profiling/debugging with possible performance costs, this next Fedora Linux release is also planning to use "_FORTIFY_SOURCE=3" compiler defenses to further bolster security. . The _FORTIFY_SOURCE=3 level allows detecting more buffer overflows and other possible security issues. GCC 12 and Glibc 2.34 have supported the _FORTIFY_SOURCE=3 level for detecting more problems at compile-time and run-time while is in good enough shape that FESCo has approved of fortify source level three replacing level two as a default compiler setting. Developers believe the improved security coverage from _FORTIFY_SOURCE=3 is well worth the small performance overhead cost and code size increase of the new level. The Fedora Engineering and Steering Committee has granted the change proposal to use "_FORTIFY_SOURCE=3" as part of the default compiler flags when building packages to help in mitigating security issues. Though some packages will revert to _FORTIFY_SOURCE=2 as packages like systemd currently have issues with the higher fortification level. The link for this article located at Phoronix is no longer available. . Fedora 38 integrates _FORTIFY_SOURCE=3 to bolster defenses against common buffer overflow vulnerabilities, enhancing security by enforcing compile-time checks.
