CISA Adds Three Actively Exploited Linux Kernel Flaws

The US Cybersecurity and Infrastructure Security Agency (CISA) added three Linux kernel security flaws to its catalog of actively exploited vulnerabilities. These vulnerabilities allow local users to access memory, escalate privileges, or disrupt systems, and are now confirmed to be used in real attacks. Red Hat has issued guidance highlighting the urgency of applying fixes. Agencies are urged to patch systems by September 21, 2026.

Why it mattersActive exploitation of key Linux kernel flaws could expose government and enterprise systems to attacks. Prompt patching is critical to prevent intrusions and service disruptions.

OpenAI pledges $1 billion for AI cyber defense program

OpenAI has pledged $1 billion in credits to help organizations defending critical U.S. infrastructure—including water utilities, electric grids, local governments, banks, and nonprofits—access its AI-powered cybersecurity tools, training, and support. The "Daybreak for Frontline Defenders" initiative aims to help these sectors strengthen their defenses as AI-driven cyberattacks become more advanced. OpenAI says it will expand the program to partner countries in the coming weeks.
