The issue was addressed with improved input validation. This issue is fixed in macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2. An app may be able to cause a denial-of-service.
AnalysisAI
Denial-of-service vulnerability in Apple macOS allows local authenticated applications to crash the system or specific services through improper input validation. Affects macOS Sequoia (before 15.7.3), Sonoma (before 14.8.3), and Tahoe (before 26.2). Attack requires local access and low privileges but no user interaction; however, real-world risk is minimal with EPSS probability of 0.02% and no public exploit identified.
Technical ContextAI
The vulnerability stems from insufficient input validation (CWE-20) in macOS kernel or system services. An unprivileged local application can trigger a denial-of-service condition by sending specially crafted input that bypasses validation checks, leading to a crash or resource exhaustion. The affected component processes input from applications running on the same system; the local attack vector and low complexity indicate the flaw is likely in a commonly-invoked system API or IPC mechanism that does not adequately sanitize parameters before use in a sensitive operation.
RemediationAI
Install the vendor-released security updates immediately: macOS Sequoia 15.7.3 or later, macOS Sonoma 14.8.3 or later, or macOS Tahoe 26.2 or later. Users should enable automatic security updates through System Settings > General > Software Update to ensure patches are applied without delay. No workarounds are documented; patching is the primary remediation. Refer to Apple's official security advisories at https://support.apple.com/en-us/125886, https://support.apple.com/en-us/125887, and https://support.apple.com/en-us/125888 for detailed update instructions and affected hardware models.
