Indian Government Issues High-Severity Security Warning for Apple Devices

CERT-In Advisory on Apple Software Vulnerabilities

The Indian Computer Emergency Response Team (CERT-In) has issued a high-severity security advisory urging users of Apple devices to update their software immediately. Reported on October 28, the warning highlights multiple security vulnerabilities affecting older software versions across a wide range of Apple products, including iPhones, iPads, Macs, Apple Watches, Apple TVs, Apple Vision Pro, and the Safari browser.

According to the advisory, these flaws could potentially allow malicious actors to execute arbitrary code, gain elevated privileges, access sensitive user information, bypass security restrictions, or cause a targeted system to crash. The vulnerabilities may be triggered when a device processes specially crafted web content, files, images, audio, video, or other vulnerable application components through memory corruption, buffer overflows, or race conditions.

Affected Apple Operating Systems and Software

The advisory applies to users and organizations running older software branches. Apple released official patches on October 26, prior to the CERT-In warning. The affected configurations include:

• iPhones: Devices running iOS versions prior to 18.7.11, 26.7.2, or 27.2, spanning models from the iPhone XS and XR up to newer generations.
• iPads: Units utilizing iPadOS versions earlier than 18.7.11, 26.7.2, or 27.2 on supported models.
• Mac Computers: Systems running macOS Sequoia (prior to 15.8.2), macOS Tahoe (prior to 26.7.2), or macOS Golden Gate (prior to 27.2).
• Apple Watch & TV: watchOS and tvOS versions prior to 27.2 on supported hardware.
• Apple Vision Pro: Headsets running visionOS versions earlier than 27.2.
• Safari: Browser versions prior to 27.2 on compatible Macs.

Practical Implications and How to Verify

Users should verify their specific device model and operating system branch to install the correct compatible update. Software updates can be checked through standard device menus:

• iPhone and iPad: Navigate to Settings > General > Software Update.
• Mac: Open System Settings > General > Software Update.
• Apple Watch, Apple TV, and Vision Pro: Check respective settings menus for available updates.

Keeping operating systems updated remains a critical measure to mitigate security risks associated with discovered software flaws. For official verification, users should consult the latest advisories published directly on the CERT-In and Apple security support portals.
