5DescriptionCVE.org
A use-after-free issue was addressed with improved memory management. This issue is fixed in Safari 26.5.2, iOS 26.5.2 and iPadOS 26.5.2, macOS Tahoe 26.5.2. Processing maliciously crafted web content may lead to an unexpected process crash.
AnalysisAI
Use-after-free memory corruption in WebKit's web content processing causes unexpected process crashes across Safari, iOS, and iPadOS on all versions prior to 26.5.2. An unauthenticated remote attacker who can lure a user to visit a maliciously crafted web page can trigger this condition, resulting in a denial-of-service via browser process termination. No public exploit code has been identified at time of analysis and the vulnerability is absent from CISA KEV, though the use-after-free class in WebKit has historically been chained with other primitives to escalate impact.
Technical ContextAI
The vulnerability is classified as CWE-416 (Use After Free), a memory-safety defect where a program continues to reference heap memory after it has been freed, producing undefined behavior - in this instance a deterministic process crash. The flaw resides in WebKit, Apple's browser rendering engine, which is shared across Safari (CPE: cpe:2.3:a:apple:safari:*:*:*:*:*:*:*:*), iOS and iPadOS (CPE: cpe:2.3:a:apple:ios_and_ipados:*:*:*:*:*:*:*:*), and macOS Tahoe (CPE: cpe:2.3:a:apple:macos:*:*:*:*:*:*:*:*). All three platforms share the same WebKit codebase, so the root-cause defect and its fix are common to all three advisories. Apple's advisory language ('improved memory management') is consistent with a lifetime-tracking or object-deallocation ordering fix in the WebKit heap allocator.
RemediationAI
Vendor-released patches are available: update to Safari 26.5.2, iOS 26.5.2, iPadOS 26.5.2, or macOS Tahoe 26.5.2. Apple's platform-specific advisories are at https://support.apple.com/en-us/127594 (Safari), https://support.apple.com/en-us/127595 (iOS and iPadOS), and https://support.apple.com/en-us/127685 (macOS). On iOS and iPadOS, updates can be applied via Settings > General > Software Update. As a compensating control prior to patching, restricting browsing to known-trusted sites reduces exposure but is operationally impractical at scale. Enterprise MDM policies that enforce Safari content restrictions or enable Lockdown Mode can further reduce attack surface on managed devices, though Lockdown Mode carries significant feature trade-offs.
