    Apple fixes exploited CoreGraphics bug (CVE-2026-86950)

    Apple fixed one memory-corruption bug in CoreGraphics for devices that stay on iOS 26, macOS Tahoe 26 and macOS Sequoia 15, and says it may have been exploited in targeted attacks. Opening or previewing a single crafted file can be enough, so these updates belong at the front of the queue.
