The Linux kernel WiFi stack has five serious flaws, according to research, which a hacker might use to execute arbitrary code or inflict a denial of service.

The vulnerability, identified as CVE-2022–42719, was brought on by a use-after-free issue in the multi-BSSID element’s ieee802 11 parse elems full function of net/mac80211/util.c. A remote authenticated adversary might leverage this issue to execute arbitrary code or bring down the system by sending a carefully crafted request. In v5.2-rc1, the CVE-2022–42719 vulnerability was first made public.

A London-based artist named Matt DesLauriers has developed a tool to generate color palettes from any text prompt, allowing someone to type in “beautiful sunset” and get a series of colors that matches a typical sunset scene, for example. Or you could get more abstract, finding colors that match “a sad and rainy Tuesday.”

DesLauriers has posted his code on GitHub; it requires a local Stable Diffusion installation and Node. JS. It’s a rough prototype at the moment that requires some technical skill to set up, but it’s also a noteworthy example of the unexpected graphical innovations that can come from open source releases of powerful image synthesis models. Stable Diffusion, which went open source on August 22, generates images from a neural network that has been trained on tens of millions of images pulled from the Internet.

Meta’s push to put computing into a headset will end in tears.

After spending two years on the ocean’s floor, Microsoft’s underwater data center had a much lower server failure rate than land-based data centers.

Using existing experimental and computational resources, a multi-institutional team has developed an effective method for measuring high-dimensional qudits encoded in quantum frequency combs, which are a type of photon source, on a single optical chip.

Although the word “qudit” might look like a typo, this lesser-known cousin of the qubit, or quantum bit, can carry more information and is more resistant to noise—both of which are key qualities needed to improve the performance of quantum networks, quantum key distribution systems and, eventually, the quantum internet.

Classical computer bits categorize data as ones or zeroes, whereas qubits can hold values of one, zero or both—simultaneously—owing to superposition, which is a phenomenon that allows multiple quantum states to exist at the same time. The “d” in qudit stands for the number of different levels or values that can be encoded on a photon. Traditional qubits have two levels, but adding more levels transforms them into qudits.

Starship could launch to orbit for the first time next month.

Entrepreneur Dennis Tito was the first-ever space tourist when he paid to fly aboard a Russian Soyuz rocket to the International Space Station (ISS) back in 2001.

Those missions will be a precursor to Starship’s eventual crewed missions to Mars, which will be partly funded by SpaceX’s space tourism launches and its Starlink internet service.

Though available only to select customers, this reaffirms faith in the blockchain method of payments.

Technology major Google has teamed up with cryptocurrency exchange platform Coinbase as it looks to allow cryptocurrency payments for its cloud services. According to a press release, the two entities will leverage their strengths towards building the next iteration of the internet, dubbed Web3.

“All bets are off if the nukes start flying,” Musk recently tweeted.

Elon Musk reportedly rejected a request from within Ukraine to extend SpaceX’s Starlink satellite internet coverage to Crimea, according to a newsletter from political analyst Ian Bremmer.

However, Musk has taken to Twitter after those reports were published and has cast doubt on their veracity by claiming that “nobody should trust Bremmer”.
