Google on Wednesday published exploit code for an unfixed vulnerability in its Chromium browser codebase that threatens millions of people using Chrome, Microsoft Edge, and virtually all other Chromium-based browsers. The proof-of-concept code exploits the Browser Fetch programming interface, a standard that allows long videos and other large files to be downloaded in the background.… Read More »
A zero-day exploit circulating online allows people with physical access to a Windows 11 system to bypass default BitLocker protections and gain complete access to an encrypted drive within seconds. The exploit, named YellowKey, was published earlier this week by a researcher who goes by the alias Nightmare-Eclipse. It reliably bypasses default Windows 11 deployments… Read More »
Both privilege escalation vulnerabilities stem from bugs in the kernel’s handling of page caches stored in memory, allowing untrusted users to modify them. They target caches in networking and memory-fragment handling components. Specifically, CVE-2026-43284 attacks the esp4 and esp6 () processes, and CVE-2026-43500 zeroes in on rxrpc. Last week’s CopyFail exploited faulty page caching in… Read More »
As noted earlier, Mozilla’s characterization of AI-assisted vulnerability discovery as a game changer has been met with massive, vocal skepticism in many quarters. Critics initially scoffed when Mozilla didn’t obtain CVE designations for any of the 271 vulnerabilities. Like many developers, however, Mozilla doesn’t obtain CVE listings for internally discovered security bugs. Instead, they are… Read More »
Publicly released exploit code for an effectively unpatched vulnerability that gives root access to virtually all releases of Linux is setting off alarm bells as defenders scramble to ward off severe compromises inside data centers and on personal devices. The vulnerability and exploit code that exploits it were released Wednesday evening by researchers from security… Read More »
Microsoft released an emergency patch for its ASP.NET Core to fix a high-severity vulnerability that allows unauthenticated attackers to gain SYSTEM privileges on devices that use the Web development framework to run Linux or macOS apps. The software maker said Tuesday evening that the vulnerability, tracked as CVE-2026-40372, affects versions 10.0.0 through 10.0.6 of the… Read More »
Researchers are warning about the risks posed by a low-cost device that can give insiders and hackers unusually broad powers in compromising networks. The devices, which typically sell for $30 to $100, are known as IP KVMs. Administrators often use them to remotely access machines on networks. The devices, not much bigger than a deck… Read More »
Coruna is also notable for its use by three distinct hacking groups. Google first detected its use in February of last year in an operation conducted by a “customer of a surveillance vendor.” The vulnerability exploited, tracked as CVE-2025-23222, had been patched 13 months earlier. In July 2025, a “suspected Russian espionage group” exploited CVE-2023-43000… Read More »
“I usually don’t say this, but patch right freakin’ now,” one researcher wrote. “The React CVE listing (CVE-2025-55182) is a perfect 10.” React versions 19.0.1, 19.1.2, or 19.2.1 contain the vulnerable code. Third-party components known to be affected include: Vite RSC plugin Parcel RSC plugin React Router RSC preview RedwoodSDK Waku Next.js According to Wiz… Read More »
The goals are sound, but ultimately they depend on users reading the dialog windows that warn of the risks and require careful approval before proceeding. That, in turn, diminishes the value of the protection for many users. “The usual caveat applies to such mechanisms that rely on users clicking through a permission prompt,” Earlence Fernandes,… Read More »
