Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the Apple iOS kernel could allow a specially crafted application to access sensitive information from the device's memory. This exposure of internal data could potentially compromise user privacy and the integrity of information stored on the device. The flaw exists within the core operating system, impacting its ability to protect memory contents.
- Vulnerable: Apple iOS kernel
- Flaw: Allows information access from memory
- Impact: Sensitive data exposure
Attack Path
How an attacker could exploit the issue
The kernel in Apple iOS, prior to version 9.3.5, could allow a malicious application to access sensitive information within the device's memory. This vulnerability can be exploited by a specially crafted application installed on the affected device. Such an application could lead to unauthorized access to confidential data stored on the device.
- Local exposure condition
- Attacker installs malicious app
- App triggers memory access; data is disclosed
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow attackers to gain unauthorized access to sensitive information residing in memory on affected Apple devices. Exploiting this issue would likely require an attacker to have already compromised the device in some way or tricked a user into installing a malicious application. The potential for sensitive data exposure presents a significant business risk, particularly if personally identifiable information or proprietary data is accessed. Organizations should prioritize addressing this vulnerability to mitigate the risk of data breaches.
- Likely attacker skill level: Unknown
- Required access or conditions: Malicious application installed
- Business risk or urgency: High
