What happened

Ars Technica's security feed (Apr–May 2026) highlights multiple high-impact incidents: a zero-day that reportedly defeats default Windows 11 BitLocker protections; at least two severe Linux vulnerabilities (including the wide-reaching "CopyFail") with urgent production patches; a month‑long supply‑chain backdoor affecting Daemon Tools and other packages (element-data), and targeted supply‑chain hits on security vendors (Checkmarx, Bitwarden). Other notable items: an emergency ASP.NET update for macOS/Linux, a nationwide Canvas outage during finals, Ubuntu infrastructure outages hampering patch
