Executive Summary

CVE-2026-4967 is a stack-based buffer overflow vulnerability in IMS (IP Multimedia Subsystem) caused by a missing bounds check. This means that the software does not properly verify the size of data before processing it, which can lead to reading data outside the intended memory area.

The vulnerability can be exploited remotely without requiring any privileges or user interaction.

Impact Analysis

This vulnerability can lead to a remote denial of service (DoS) attack, causing the affected system or device to crash or become unresponsive.

No additional execution privileges are needed to exploit this vulnerability, making it easier for attackers to disrupt services.

Mitigation Strategies

To mitigate CVE-2026-4967, it is recommended to update affected systems to patched versions of the software. This vulnerability affects IMS implementations on multiple chipsets and Android versions 13 through 16.

  • Apply security updates provided by the vendor (UNISOC) for the affected chipsets.
  • Upgrade Android operating systems to versions where this vulnerability is fixed.
  • Restrict network access to IMS services to trusted sources to reduce exposure.
