  - A flaw was found in WebKitGTK. This vulnerability allows remote, user-assisted information disclosure that
    can reveal any file the user is permitted to read via abusing the file drag-and-drop mechanism where
    WebKitGTK does not verify that drag operations originate from outside the browser. (CVE-2025-13947)

  - Out of bounds memory access in ANGLE in Google Chrome on Mac prior to 143.0.7499.110 allowed a remote
    attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity:
    High) (CVE-2025-14174)

  - The issue was addressed with improved memory handling. This issue is fixed in Safari 26.1, iOS 18.7.2 and
    iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Tahoe 26.1, tvOS 26.1, visionOS 26.1, watchOS 26.1.
    Processing maliciously crafted web content may lead to memory corruption. (CVE-2025-43431, CVE-2025-43433)

  - A use-after-free issue was addressed with improved memory management. This issue is fixed in Safari 26.1,
    iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Tahoe 26.1, visionOS 26.1, watchOS 26.1.
    Processing maliciously crafted web content may lead to an unexpected Safari crash. (CVE-2025-43438)
