Apple Patches 30+ iOS, macOS, Safari Flaws, Including AI-Discovered WebKit Bugs

The four vulnerabilities are part of nearly 30 vulnerabilities that have been patched in WebKit, an open-source web browser engine developed by Apple. Others include a use-after-free issue in WebKit Canvas (CVE-2026–43720) and a vulnerability that could be exploited by a malicious website to process restricted web content outside the sandbox (CVE-2026–43725).

Apple has also remediated three bugs that could be exploited by a malicious app to leak sensitive kernel state (CVE-2026–43722), cause unexpected system termination or write kernel memory (CVE-2026–43724), or corrupt kernel memory (CVE-2026–39868). Security researcher Hyunwoo Kim, who discovered Dirty Frag, has been credited with discovering and reporting CVE-2026–43724 and CVE-2026–43722.

The updates are available for iOS 26.5.2, iPadOS 26.5.2, macOS Tahoe 26.5.2, and Safari 26.5.2. None of the patched vulnerabilities has been disclosed as actively exploited in the wild.

Microsoft extends Windows Server 2022 hotpatching until October 2027

Microsoft has extended Windows Server 2022 hotpatching until October 2027, one year after the mainstream end date of October 2026.

This comes with the following caveat: extended support is only available for systems running Windows Server 2022 Datacenter: Azure Edition that are enrolled in hotpatch updates. This change is effective immediately, and the existing hotpatch cadence will remain unchanged through October 2027.

On systems where hotpatching is enabled, Windows deploys security updates by patching the in-memory code of running processes without restarting them after each installation or rebooting the device.

Two South Korean companies named Samsung Electronics and SK Hynix now manufacture roughly two-thirds of the memory chips inside almost every digital device on Earth — produced inside a country whose 1953 per-capita income was lower than Somalia’s or Haiti’s

Open any device built in the past five years, look inside its memory subsystem, and the chips you find were almost certainly fabricated in one of three South Korean industrial cities — Hwaseong, Pyeongtaek, or Icheon — by one of two companies whose combined market capitalisation now exceeds $700 billion. The historical improbability of this situation is not a matter of degree but of category. Korea in 1953 did not have a semiconductor industry, a precision manufacturing tradition, an advanced engineering workforce, or the kind of capital markets that could finance industrial development. It had a per-capita income lower than essentially every other country whose subsequent economic trajectory has been studied by development economists, a primarily agricultural economy substantially destroyed by three years of active warfare, and a small population (~20 million) whose adult literacy rate stood at approximately 20 percent. The proposition that, 72 years later, two companies headquartered in the same country would manufacture the memory chips inside Apple’s iPhones, Google’s Pixel devices, Microsoft’s data centres, Nvidia’s AI accelerators, Tesla’s autonomous-driving computers, and essentially every other major piece of digital hardware sold globally — would have been considered, by any reasonable observer in 1953, structurally impossible.

When mitochondria grow abnormally long, leaked RNA may activate anti-tumor immune responses

Researchers from the University of Osaka have demonstrated that mitochondrial hyperfusion, when induced by low levels of DRP1 or cellular stress, activates an immune response through the RIG-I–MAVS pathway. Dependent on the involvement of the BAX protein, the release of mitochondrial RNA into the cytosol enhanced natural killer cell cytotoxicity and reduced tumor growth in a xenograft model. The findings, published in Cell Reports, provide new possibilities for cancer research and treatment.

Mitochondria are constantly dividing and fusing within our cells, reshaping themselves to keep up with the cell’s changing needs. Sometimes, though, things go awry, and mitochondria can grow abnormally long. Are these long mitochondria harmful, or might they serve a purpose?

Mitochondria also act as signaling centers, helping the cell sense and respond to trouble. When mitochondria are hyperfused, for example in the stressed, abnormally long state described above, they release their genetic material into the cytosol, where the cell treats it as a warning sign in the same way it would treat a virus.

New Wright-Patt supercomputer calculates in a day what would take average laptop 500 years

Wright Patterson Air Force Base has a new advanced problem solver for future military systems and weapons. It’s called the Flyer, named in honor of Wilbur and Orville Wright and their research in aerodynamics.

The Flyer is the Pentagon’s latest supercomputer. It has more than 186,000 cores able to process millions of advanced calculations in a few seconds.

David Shahady, deputy director of the Air Force Research Laboratory’s Digital Capabilities Directorate, equated the abilities of this unit to a pop-culture sci-fi character.
