Musk Concludes Testimony At OpenAI Trial

An anonymous reader quotes a report from CNBC: Elon Musk wrapped up his testimony on Thursday as the trial in his lawsuit against OpenAI CEO Sam Altman continued into its fourth day. OpenAI's attorney, William Savitt, cross-examined Musk in the morning. He asked Musk about the capped nature of Microsoft's investments in OpenAI, his involvement in negotiations about the company's structure, and whether he knew about the OpenAI nonprofit's recent initiatives. "I don't know what's going on at OpenAI," Musk testified. Savitt also asked Musk about his competing artificial intelligence startup, xAI. While not the main focus of the case, Musk said it is "partly" true that xAI used some of OpenAI's models to train its own models, a process known as distilling. Musk also suggested that xAI has used OpenAI's technology to help build the company. Musk sued OpenAI, Altman, and Greg Brockman, the company's president, in 2024, alleging that they went back on their commitments to keep the artificial intelligence company a nonprofit and to follow its charitable mission. He claims that the roughly $38 million he donated to seed OpenAI, a company he co-founded, was used for unauthorized commercial purposes. Once Musk wrapped up his testimony after roughly two hours of questioning on Thursday, his attorneys called Jared Birchall, who manages Musk's billions at his family office, as their next witness. Birchall testified about his knowledge of Musk's specific donations to OpenAI. Judge Yvonne Gonzalez Rogers oversaw the proceedings from federal court in Oakland, California. The trial will resume on Monday.

US Senators Ban Themselves From Prediction Markets Trading

The U.S. Senate unanimously passed a rule banning senators from trading on prediction markets effective immediately. CNBC reports: The move came amid rising concern about insider trading on prediction market platforms such as Kalshi and Polymarket, and about event contracts that can involve death or violence. On April 22, Kalshi said it had suspended and fined one U.S. Senate candidate and two candidates for the House of Representatives for political insider trading on their own campaigns. Earlier on Thursday, a group of Democratic members of Congress called on the Commodity Futures Trading Commission to issue a rule "that prevents insider trading and corruption in the market and prohibits event contracts on the outcome of elections, war and military actions in the U.S. or abroad, sports, and government actions without a valid economic hedging interest." Kalshi and Polymarket both praised the Senate's action. "I applaud the Senate for passing this resolution to ban Senators and their offices from trading on prediction markets," Kalshi CEO Tarek Mansour wrote in a post on X. "Kalshi already proactively blocks members of congress and enforces against insider trading. This is a great step to increase trust in our markets by making it an industry standard," Mansour said. "Now, let's pass this in the House!" Polymarket, in its own post on X, said, "We're in full support of this. Our Rulebook & Terms of Service already prohibit such conduct, but codifying this into law is a step forward for the industry. Happy to help move this forward however we can."

New Linux 'Copy Fail' Vulnerability Enables Root Access On Major Distros

A newly disclosed Linux kernel flaw dubbed "Copy Fail" can let a local, unprivileged attacker gain root access on major Linux distributions, with researchers claiming the bug affects kernels shipped since 2017. "The POC exploit works out of the box today, but a future version that can escape from containers like Docker is promised soon," writes Slashdot reader tylerni7. "Technical details are available here." Slashdot reader BrianFagioli shares a report from NERDS.xyz: A newly disclosed Linux kernel vulnerability called Copy Fail (CVE-2026-31431) allows an unprivileged user to gain root access using a tiny 732-byte script, and it works with unsettling consistency across major distributions. Unlike older exploits that relied on race conditions or fragile timing, this one is a straight-line logic flaw in the kernel's crypto subsystem. It abuses AF_ALG sockets and splice to overwrite a few bytes in the page cache of a target file, such as /usr/bin/su. Because the kernel executes from the page cache, not directly from disk, the attacker can inject code into a setuid binary in memory and immediately escalate privileges. What makes this especially concerning is how quiet it is. The file on disk remains unchanged, so standard integrity checks see nothing wrong, while the in-memory version has already been tampered with. The same primitive can also cross container boundaries since the page cache is shared, raising the stakes for multi-tenant environments and Kubernetes nodes. The underlying issue traces back to an in-place optimization added years ago, now being rolled back as part of the fix. Until patched kernels are widely deployed, this is one of those bugs that feels less like a theoretical risk and more like a practical, reliable path to full system compromise.
