Apple users in India have been issued a serious security warning by the central government, urging them to immediately update their devices. The Indian Computer Emergency Response Team (CERT-In), under the Ministry of Electronics and Information Technology, has detected multiple critical vulnerabilities in Apple products and classified the alert as high severity.

The advisory, catalogued as CIVN-2025-0163, points out serious flaws in various Apple operating systems including iOS, iPadOS, macOS, watchOS, tvOS, and visionOS. These vulnerabilities could allow attackers to access sensitive information, execute arbitrary code, bypass security restrictions, elevate privileges, or even cause denial-of-service (DoS) conditions that render the device inoperable.

According to CERT-In, the vulnerabilities affect devices running outdated versions—specifically, iOS versions below 18.6, iPadOS below 17.7.9 or 18.6, macOS Sequoia below 15.6, macOS Sonoma below 14.7.7, macOS Ventura below 13.7.7, watchOS below 11.6, tvOS below 18.6, and visionOS below 2.6. These flaws stem from issues such as use-after-free bugs, out-of-bounds memory access, buffer overflows, race conditions, logic errors, and insufficient input validation.

In many cases, attackers could exploit these weaknesses simply by sending specially crafted requests to compromised systems. If successful, such attacks could result in data theft, unauthorized system access, and permanent device damage.

To counter the threat, Apple has already released security patches through its official update channels. CERT-In advises all users to apply these updates immediately. Users should also practice good cyber hygiene by avoiding untrusted applications, not clicking on suspicious links, and monitoring their devices for unusual activity.

With cyberattacks becoming increasingly frequent and sophisticated, this advisory underscores the urgent need for proactive digital safety measures among both individual and enterprise Apple users.
