  - 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)

  - A buffer overflow issue was addressed with improved memory handling. This issue is fixed in Safari 26.2,
    iOS 18.7.3 and iPadOS 18.7.3, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, visionOS 26.2. Processing
    maliciously crafted web content may lead to an unexpected process crash. (CVE-2025-43501)

  - A use-after-free issue was addressed with improved memory management. This issue is fixed in Safari 26.2,
    iOS 18.7.3 and iPadOS 18.7.3, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2,
    watchOS 26.2. Processing maliciously crafted web content may lead to arbitrary code execution. Apple is
    aware of a report that this issue may have been exploited in an extremely sophisticated attack against
    specific targeted individuals on versions of iOS before iOS 26. CVE-2025-14174 was also issued in response
    to this report. (CVE-2025-43529)

  - A race condition was addressed with improved state handling. This issue is fixed in Safari 26.2, iOS
    18.7.3 and iPadOS 18.7.3, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, watchOS
    26.2. Processing maliciously crafted web content may lead to an unexpected process crash. (CVE-2025-43531)
