CVE-2025-24135 is a high-severity vulnerability affecting Apple macOS, particularly fixed in version Sequoia 15.3. This vulnerability allows an app to potentially gain elevated privileges due to inadequate message validation. The CVSS score of 7.8 emphasizes the importance of addressing this issue promptly.
Organizations using macOS should be aware of the real-world risk posed by this vulnerability. Attackers may leverage this flaw to escalate their privileges without proper authorization, leading to unauthorized access and potential data breaches. Therefore, organizations should prioritize patching immediately.
As of now, there is no confirmed public exploit available for this vulnerability, but its high CVSS score indicates a serious risk that must not be overlooked. Immediate action is essential to safeguard systems and data.
With the potential for exploitation, organizations must ensure that their macOS environments are updated to the latest version to mitigate risks associated with CVE-2025-24135.
Vulnerability Details
This vulnerability allows an app to gain elevated privileges due to improved message validation that was addressed in macOS Sequoia 15.3. The vulnerability has a CVSS score of 7.8, indicating high severity and significant impact on confidentiality, integrity, and availability.
The vulnerability was published on January 27, 2025, and it falls under CWE-276, which pertains to improper handling of messages leading to potential privilege escalation.
Technical Analysis
The root cause of this vulnerability stems from inadequate validation of messages within the macOS environment. Attackers can exploit this vulnerability locally, requiring low complexity and no privileges initially, but necessitating user interaction to execute the attack.
If exploited, the impact on confidentiality, integrity, and availability is classified as high, as attackers could gain unauthorized access to sensitive information and disrupt system operations.
Risk & Impact Analysis
The potential deployment risk for organizations running affected versions of macOS is significant. With a CVSS score of 7.8, organizations face a high likelihood of successful exploitation if they do not apply the necessary patches. The blast radius includes any systems where the vulnerability exists, emphasizing the urgency of patching.
Due to the nature of this vulnerability, organizations should assess their exposure and prioritize remediation based on their risk tolerance and the criticality of the systems affected. The urgency to address this vulnerability is underscored by its high severity and potential impact.
