Description
In Modem, there is a possible system crash due to a missing bounds check. This could lead to remote escalation of privilege, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: MOLY01911177; Issue ID: MSV-10122.

AI Analysis

Impact

The vulnerability is a missing bounds check in the Modem component, leading to a potential system crash. If a user equipment (UE) connects to a rogue base station controlled by an attacker, this flaw can enable remote escalation of privilege without requiring additional execution privileges. User interaction is necessary for exploitation, and the weakness is classified as CWE-787.

Affected Systems

The affected product is the MediaTek chipset used in Modem hardware. No specific firmware or hardware revision numbers are listed, so all versions of MediaTek chipsets that include the vulnerable Modem component are potentially impacted.

Risk and Exploitability

The EPSS score is not available and the vulnerability is not listed in the CISA KEV catalog, indicating no currently observed exploits. However, exploitation requires the attacker to control a base station and a UE must connect to it. The missing bounds check can cause a crash that may be leveraged for privilege escalation, representing a moderate to high risk for devices that rely on these chipsets for cellular connectivity.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the MediaTek patch identified by MOLY01911177 or update the affected firmware to the latest version that resolves the bounds check issue.
  • Verify that users’ devices are not connecting to known rogue base stations by monitoring the network environment and restricting communication to trusted base stations.
  • Enforce strict authentication and cryptographic validation on the UE side, ensuring that connections to unidentified or untrusted base stations are rejected or flagged for review.
