Apple Patches 163 Vulnerabilities in iOS 27.2 Including Multiple WebKit Code Execution Flaws

Apple released iOS 27.2 and iPadOS 27.2 on October 26, addressing 163 vulnerabilities across its mobile platforms. More than 30 of these issues reside in the WebKit engine, with several enabling remote code execution simply by visiting a malicious webpage. The update also resolves two sandbox escapes, one in WebKit's process model and another in the App Store reported by Cisco Talos researchers. Four privacy-related fixes include a flaw in Apple Intelligence that could expose sensitive user data to remote attackers. On the same day, Apple issued iOS 18.7.11 for older devices such as the iPhone XS and XR, fixing a CoreGraphics out-of-bounds write tracked as CVE-2026-86950 that had already been exploited in a highly sophisticated targeted attack. The company stated that none of the 163 flaws in the main release have been observed in the wild.

Apple Releases iOS 27.2 and iPadOS 27.2, Patching 163 Vulnerabilities Including Exploited Flaws in Older Versions

Apple has issued security updates for iOS and iPadOS, addressing a wide range of vulnerabilities across current and legacy operating systems. The iOS 27.2 and iPadOS 27.2 releases fix 163 CVEs affecting WebKit, the kernel, and image processing components. Older branches received targeted patches, with iOS 26.7.2 resolving 134 issues and iOS 18.7.11 addressing three vulnerabilities that include an actively exploited flaw. Specific fixes cover remote code execution risks in WebKit and ImageIO, plus sandbox bypasses. The updates were published on October 26, 2026, and apply to both iPhone and iPad devices. Apple also published detailed security content advisories for each branch.

Censys Exposes DarkSword iOS Exploit Platform and Coruna Crypto Wallet Stealer

Censys has disclosed the inner workings of DarkSword, a commercial platform that sells remote access to iOS devices, along with its associated malware Coruna that targets cryptocurrency wallet recovery keys. The infrastructure was exposed between September 15 and 17, allowing researchers to analyze the full attack chain starting from a WebKit and JavaScriptCore exploit delivered through the browser. After escaping the Safari sandbox and reaching the kernel, the platform deploys three layers including a flag, controller, and main implant. Coruna then scans the device for BIP39-compliant seed phrases stored in photos and Apple Notes across 19 targeted wallet applications such as MetaMask, Phantom, Trust Wallet, Coinbase, Exodus, imToken, Bitpie, and BitKeep. The exposed server contained 11 victim recovery keys, 179 directories of extracted data, and 75 operator accounts, indicating a structured commercial operation with agent accounts, commissions, and device quotas. Confirmed infections affect devices running iOS 16.1 and 16.3.1, while Apple has extended patches to additional iOS 18 devices. Maintaining updated iOS versions remains the primary defense against this threat.

Apple Releases iOS 27 and iPadOS 27 with Fixes for 126 Vulnerabilities

Apple has issued macOS Tahoe 26.6.2, addressing a total of 28 security vulnerabilities tracked under CVE identifiers. The update resolves three kernel-level issues, among them a Use After Free flaw tracked as CVE-2026-65343, an out-of-bounds memory read in CVE-2026-65349, and a memory corruption problem in CVE-2026-65330. Twenty-one of the fixed vulnerabilities affect the WebKit engine, with additional patches applied to Audio, ImageIO, and IOGPUFamily components. The release incorporates fixes that were previously tested in the macOS Golden Gate 27 beta. On the following day, Apple also shipped Safari 26.6.1 for macOS Sonoma and macOS Sequoia, eliminating the same set of 21 WebKit vulnerabilities.
