Is Your iPhone Safe? iOS 26.2 Patch Notes & Exploits Fixed.

Summary: Apple released iOS 26.2 on December 12, 2025, patching 25+ vulnerabilities across WebKit, Kernel, FaceTime, and core frameworks. Two WebKit flaws (CVE-2025-43529 and CVE-2025-14174) were actively exploited in sophisticated spyware attacks targeting specific individuals. The update also fixes a critical Kernel bug allowing apps to gain root privileges (CVE-2025-46285). All iPhone 11 and later devices should update immediately to protect against memory corruption, arbitrary code execution, and data exposure risks.

Apple released iOS 26.2 and iPadOS 26.2 on December 12, 2025, addressing over 25 security vulnerabilities across critical system components. Two WebKit flaws were already being exploited in highly targeted attacks before the patch arrived, making this one of the most urgent iPhone updates of 2025. If you’re running iOS 26 or earlier on an iPhone 11 or newer device, updating now isn’t optional, it’s essential.

What Is iOS 26.2 and When Was It Released?

iOS 26.2 is Apple’s latest security-focused update that shipped December 12, 2025, following two release candidate builds tested by developers. While the update includes minor feature additions like one-time AirDrop codes and automatic Podcasts chapter generation, the primary focus is patching a dangerous collection of vulnerabilities discovered by Apple’s Security Engineering team, Google Threat Analysis Group, and independent researchers.

Release Timeline and Compatible Devices

The update is available for:

• iPhone 11 and all newer models
• iPad Pro 12.9-inch (3rd generation and later)
• iPad Pro 11-inch (1st generation and later)
• iPad Air (3rd generation and later)
• iPad (8th generation and later)
• iPad mini (5th generation and later)

Apple confirmed the patches went live across all regions simultaneously, with no staggered rollout.

The Two Zero-Day Exploits Already Under Attack

Apple confirmed two WebKit vulnerabilities were exploited in “extremely sophisticated attacks” against specific targeted individuals before iOS 26.2 launched. Security researchers believe these flaws were weaponized as part of a commercial spyware campaign due to their technical characteristics and disclosure timeline.

CVE-2025-43529: WebKit Use-After-Free Vulnerability

This memory management flaw allows attackers to execute arbitrary code on your iPhone simply by tricking you into visiting a malicious website. Google’s Threat Analysis Group discovered this vulnerability being actively exploited and reported it to Apple.

Technical details: A use-after-free bug occurs when code continues accessing memory after it’s been freed, creating exploitable conditions for code injection. Apple addressed this with improved memory management in the WebKit rendering engine.

CVE-2025-14174: WebKit Memory Corruption Flaw

This companion vulnerability allows attackers to corrupt device memory through crafted web content. Both Apple and Google Threat Analysis Group identified this flaw, suggesting coordinated investigation efforts.

Interestingly, Google patched the identical vulnerability in Chrome on December 10 two days before Apple’s iOS 26.2 release. This timing gap created a 48-hour window where attackers knew exactly what to target on unpatched iPhones.

Who Discovered These Exploits?

Google Threat Analysis Group (TAG) played a central role in uncovering both zero-days. TAG specializes in tracking government-backed attackers and commercial spyware vendors who develop exploits for sale to nation-states and private entities. Their involvement strongly indicates these weren’t random attacks but highly targeted surveillance operations.

Complete List of 25+ Security Fixes in iOS 26.2

Beyond the two zero-days, iOS 26.2 patches 23 additional vulnerabilities across 15 system components. Here are the most critical fixes:

Critical Kernel Vulnerability (CVE-2025-46285)

An integer overflow in the iOS kernel could allow malicious apps to gain root privileges at the highest level of system access. Researchers Kaitao Xie and Xiaolong Bai from Alibaba Group discovered this flaw.

What Apple fixed: The company addressed the issue by adopting 64-bit timestamps, preventing the integer overflow condition.

FaceTime Caller ID Spoofing Risk

CVE-2025-46287 allowed attackers to spoof their FaceTime caller ID through an inconsistent user interface issue. Two researchers, one anonymous and Riley Walz independently discovered this vulnerability that could enable sophisticated social engineering attacks.

App Store Payment Token Exposure

A permissions issue (CVE-2025-46288) let apps access sensitive payment tokens stored on your device. Apple implemented additional restrictions to prevent unauthorized apps from reaching this financial data.

Hidden Photos Authentication Bypass

Perhaps the most privacy-invasive flaw: CVE-2025-43428 allowed access to photos in the Hidden Photos Album without authentication. Michael Schmutzer of Technische Hochschule Ingolstadt and an anonymous researcher uncovered this configuration weakness.

Additional notable fixes:

• Foundation spellcheck API exploit (CVE-2025-43518): Apps could inappropriately access files
• Screen Time logging issues (CVE-2025-46277, CVE-2025-43538): Apps gained access to Safari history and sensitive user data
• Messages privacy controls (CVE-2025-46276): Information disclosure through inadequate privacy controls
• curl vulnerabilities (CVE-2024-7264, CVE-2025-9086): Open-source code issues affecting multiple platforms
• Multiple WebKit crashes: Four additional WebKit bugs causing process crashes and memory corruption

How Attackers Exploited These Vulnerabilities

Sophisticated Spyware Campaign Targeting

Security experts assess that the dual WebKit vulnerabilities were chained together in a sophisticated attack chain. The first flaw (CVE-2025-43529) enabled initial code execution, while the second (CVE-2025-14174) corrupted memory to bypass iOS security protections.

This type of multi-stage exploit is characteristic of commercial spyware like NSO Group’s Pegasus or similar surveillance tools. These products are sold to governments and private entities for targeted monitoring of journalists, activists, politicians, and dissidents.

The 48-Hour Patch Window Attackers Abuse

Google patched the same WebKit vulnerabilities in Chrome on December 10, 2025. This created a dangerous knowledge gap: attackers knew exactly what to target on iPhones for 48 hours before Apple’s patch arrived.

Research shows organizations typically need 38 to 150 days to fully deploy security updates. Attackers weaponize disclosed vulnerabilities in hours or days, creating an exploitation window that favors offense over defense.

What Happens If You Don’t Update?

Real-World Risk Assessment

If you visit a compromised website while running iOS 26 or earlier, attackers exploiting CVE-2025-43529 could:

• Execute arbitrary code on your device
• Install persistent spyware without your knowledge
• Access your photos, messages, location, and encrypted data
• Monitor your communications in real-time

The Kernel vulnerability (CVE-2025-46285) is equally dangerous. A malicious app installed from any source could gain root privileges and control your entire device.

Data Privacy Implications

The Hidden Photos bypass (CVE-2025-43428) and Messages disclosure bug (CVE-2025-46276) expose your most private content. These aren’t theoretical risks, they’re confirmed vulnerabilities that Apple documented in its security bulletin.

iOS 26.2 vs. Previous Security Updates: What Changed?

Since 2023, Apple has disclosed 17 different WebKit vulnerabilities exploited in the wild. iOS 26.2 marks the fifth major security update in 2025 addressing actively exploited zero-days.

What makes this release particularly critical:

• Dual zero-days simultaneously exploited (rare in iOS history)
• Google TAG involvement (indicates nation-state or commercial spyware activity)
• Kernel root privilege escalation (one of the most dangerous vulnerability types)
• Pre-authentication privacy bypasses (Hidden Photos, FaceTime spoofing)
