CVE-2025-21042

Samsung Mobile Devices

Samsung mobile devices contain an out-of-bounds write vulnerability in libimagecodec.quram.so. This vulnerability could allow remote attackers to execute arbitrary code.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • US federal civilian agencies are required to remediate it by 2025-12-01. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
