The kernel in Apple iOS before 9.3.5 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. This vulnerability is classified as high severity with a CVSS score of 7.8. Organizations using affected iOS versions must prioritize remediation to prevent exploitation.
Risk to organizations includes unauthorized access to sensitive data, potential service disruptions, and a compromise of device integrity. Attackers may leverage this vulnerability to execute arbitrary code, leading to further exploitation of the affected system.
Current exploitation status indicates that there are known exploits available. Organizations should act swiftly to mitigate this vulnerability to avoid potential damage.
Organizations should prioritize patching immediately.
Vulnerability Details
The kernel in Apple iOS before 9.3.5 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. This vulnerability is associated with CWE-787, indicating improper access control leading to memory corruption.
The CVSS score is 7.8, indicating high severity. The vulnerability can be exploited locally, requiring user interaction, but does not require any privileges. The high impact on confidentiality, integrity, and availability makes this a critical issue for organizations.
Technical Analysis
The root cause of this vulnerability lies in the kernel's handling of memory, which allows for arbitrary code execution. The attack vector is local, meaning the attacker must have access to the device, and the attack complexity is low. User interaction is required to trigger the exploit, making it essential for users to avoid malicious applications.
The impacts on confidentiality, integrity, and availability are significant. Successful exploitation could lead to unauthorized access to sensitive data and control over the affected device.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is high, particularly in environments where users may be exposed to untrusted applications. The potential blast radius includes any device running iOS versions prior to 9.3.5, which could be exploited to gain unauthorized access or cause service disruptions.
Organizations should assess their exposure to this vulnerability, especially if they maintain legacy systems that may not have been updated. The urgency for remediation is critical, given the CVSS score and known exploitation status.
Exploitation Status
