[The most severe Linux threat to surface in years catches the world flat-footed](https://arstechnica.com/security/2026/04/as-the-most-severe-linux-threat-in-years-surfaces-the-world-scrambles/) A critical local privilege escalation vulnerability, dubbed “Copy Fail” (CVE-2026-31431), allows unprivileged attackers to gain root access across virtually all major Linux distributions. By abusing AF_ALG sockets to overwrite the page cache of target files in memory, the exploit executes cleanly without altering files on disk, making it nearly invisible to standard integrity checks. Exploit code is already public, sending data centers and container-heavy environments scrambling to patch.

[Apple’s iPhone revenue jumps to $57 billion despite chip shortages](https://www.theverge.com/tech/921527/apple-iphone-revenue-q2-2026-earnings) Apple reported its best March quarter ever, pulling in $111.2 billion in total revenue and a 19 percent increase in profit. iPhone sales jumped 22 percent to $57 billion, with CEO Tim Cook noting that demand was “off the charts” even as the company navigates a looming “RAMaggedon” chip shortage across its supply chain. The results arrive just ahead of Cook’s September retirement, when hardware chief John Ternus will take over.
