AI Analysis

Impact

The flaw arises from improper handling of internal state within Safari’s state management logic. When maliciously crafted web content is processed, it can trigger an unexpected crash, resulting in a denial‑of‑service that interrupts user activity and risks loss of unsaved data (CWE‑120).

Affected Systems

Apple devices running iOS and iPadOS before 18.7.10 and 26.6.1, Safari before 26.6.1, and macOS Tahoe before 26.6.2 are affected until the system is updated to the fixed releases listed above.

Risk and Exploitability

The vulnerability can be triggered simply by loading malicious web content; the attacker only needs to craft a URL or website. The EPSS score is less than 1%, and the vulnerability is not listed in CISA’s KEV catalog. The impact is restricted to availability, producing a Safari crash with no privilege elevation or data compromise (CWE‑120). The CVSS score is 4.3. Updating to the patched releases mitigates the risk.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the device operating system to a version that includes the Safari fix (iOS 18.7.10 or later, iPadOS 18.7.10 or later, iOS 26.6.1 or later, iPadOS 26.6.1 or later, macOS Tahoe 26.6.2 or later).
  • If a system update is unavailable, limit browsing to trusted sites and consider disabling JavaScript in Safari to reduce the likelihood of a crash.
  • When updates or feature restrictions cannot be applied, use an alternate browser that is not affected by this defect as a temporary workaround.
