Race Condition Vulnerability in macOS by Apple

CVE-2026-28817

What is CVE-2026-28817?

CVE-2026-28817 is a race condition vulnerability found in macOS, developed by Apple. This issue arises from improper state handling within the operating system, particularly affecting sandboxed processes. Sandboxing is a critical security mechanism that isolates applications, restricting their access to the system and sensitive data. When a sandboxed process can circumvent these restrictions, it opens the door for unauthorized actions that could severely compromise the integrity and confidentiality of an organization's data and systems. The vulnerability has been addressed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, and macOS Tahoe 26.4, but any systems still operating prior versions remain at risk.

Potential impact of CVE-2026-28817

1. Unauthorized Access: Attackers exploiting this vulnerability may gain the ability to execute unauthorized actions within the operating system, which could lead to data leaks or unauthorized manipulation of resources.

2. Compromise of Sensitive Data: By circumventing sandbox restrictions, malicious processes could potentially access sensitive user data, leading to privacy breaches and compliance violations.

3. System Stability and Integrity Risks: The exploitation of this flaw could destabilize affected systems, potentially leading to crashes or malfunctioning applications, which can disrupt organizational operations and impact user trust.
