Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability exists in the modem interface driver of Samsung Android devices that can lead to a system-wide disruption. If an attacker gains the necessary radio permissions, a flaw in how the driver handles input can cause a format string bug. This bug can result in a kernel panic, effectively crashing the operating system and impacting device stability.
- Modem interface driver
- Missing input validation
- Operating system crash
Attack Path
How an attacker could exploit the issue
This vulnerability exists within a modem interface driver, which could allow an attacker to gain control of the system. This is achieved by exploiting a missing input validation, leading to a format string bug that ultimately causes a kernel panic. The impact on affected organizations could include system instability and potential unauthorized control.
- Radio permission is gained.
- Attacker triggers a format string bug.
- Results in kernel panic.
Live Threat
Current exploitation, exposure, and threat context
A vulnerability in Samsung Android devices could allow an attacker with local access to cause a kernel panic. This occurs due to a format string bug in the modem interface driver, which can be triggered if radio permissions are obtained. The potential impact includes system instability and denial of service.
- Attacker skill level: Moderate
- Required access: Local access, radio permission
- Business risk: System instability, denial of service
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability presents a risk to Samsung Android devices due to a format string bug in the modem interface driver. Successful exploitation could lead to a kernel panic, potentially impacting system stability and availability. The vulnerability is classified as internal, meaning an attacker would need local access to the device to exploit it.
- Identify affected Samsung Android devices.
- Reduce exposure by isolating affected systems.
- Apply vendor updates and validate fixes.
- Monitor for related system instability.
