Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the modem interface driver of Samsung Android devices can allow unauthorized code execution. This flaw arises from insufficient boundary checking within a buffer handling function. Exploitation could lead to significant business risk by compromising system integrity and data confidentiality.
- Vulnerable modem interface driver
- Missing buffer boundary checks
- Arbitrary code execution possible
Attack Path
How an attacker could exploit the issue
This vulnerability exists within the modem interface driver on Samsung Android devices. Exploitation requires an attacker to have local access or be able to execute code on the device. The vulnerability allows for out-of-bounds reads, which can lead to arbitrary code execution by dereferencing an invalid function pointer.
- Local access to the device is required.
- An attacker triggers the vulnerability.
- Arbitrary code execution results.
Live Threat
Current exploitation, exposure, and threat context
The identified vulnerability in Samsung mobile devices could allow an attacker to execute arbitrary code. This is due to an out-of-bounds read in the modem interface driver that results in the dereferencing of an invalid function pointer. The vulnerability has been classified as internal, meaning it requires local access to the device.
- Likely attacker skill level: Low
- Required access or conditions: Local device access
- Business risk or urgency: High impact, consider urgent
Priority actions
Operational Fix
