Apple Urges Users to Update: Medium-Severity Vulnerability Affects Wide Range of Devices
A serious vulnerability has been discovered in Apple's operating systems, affecting a wide range of devices. The flaw, classified as medium-severity, could cause denial-of-service conditions, corrupt process memory, and destabilize apps. CERT-In has issued an advisory urging users to install the latest software updates immediately.
The vulnerability, identified as CVE-2025-43400, lies in the FrontParser component of Apple's operating systems. It can be triggered by processing a maliciously crafted font on vulnerable systems. This affects Apple devices running iOS and iPadOS versions prior to 18.7.1 and 26.0.1, and macOS versions prior to the specified updates. Even Apple's newest visionOS platform is impacted in versions prior to 26.0.1.
Companies relying on Apple devices could also face disruptions if the flaw is exploited. The affected companies are those using Apple devices running vulnerable OS versions before updating to the patched releases. This includes iOS 18.7.1 or macOS Tahoe 15.7.1. Therefore, companies that use Apple hardware without these updates installed could suffer from these exploitations.
To ensure their devices remain secure, users are advised to install automatic updates. This will protect against the vulnerability and prevent potential service outages or data manipulation. Apple has released updates to address the issue, and users should prioritize installing these updates as soon as possible.
