Apple has capped the number of open bug-bounty reports researchers can submit after being flooded with low-quality and sometimes entirely fabricated vulnerabilities generated by AI. MacRumors reports: The Financial Times learned of the limit after cybersecurity startup Bynario used ChatGPT to locate more than 50 macOS bugs in three weeks. Bynario found a privilege escalation exploit that could let an attacker get unrestricted access to a Mac, but was unable to report it because Apple limited the number of bug reports Bynario could submit. Bynario sent eight reports to Apple in 2025, and another five in 2026 before hitting a restriction. Bynario's founder said it is a "very difficult time in the industry" because companies are being "flooded by the sheer amount of bugs." Apple has since been in contact with Bynario and is reviewing the company's submissions. While Apple now has a cap on the number of open submissions a researcher can have, researchers can request an increase to make sure Apple's security team doesn't miss a critical vulnerability.

Slashdot reader prisoninmate shares this report from 9to5Linux: Coming ten days after the previous Linux kernel security update, which only fixed 12 vulnerabilities that may lead to a privilege escalation, denial of service, or information leaks, the new Debian 13 Linux kernel security update is a massive one, and it patches no less than 68 security vulnerabilities in the Linux 6.12 LTS kernel. Debian 13 "Trixie" kernel security update are CVE-2026-64530, a use-after-free in the traffic-control subsystem leading to remote denial-of-service with potential for remote code execution, and CVE-2026-64531 (a.k.a. OVSwrap), a local-root vulnerability in the Open vSwitch datapath leading to local privilege escalation to root... All Debian 13 "Trixie" users are urged to update their installations to Linux kernel 6.12.100-1 as soon as possible.
