CVE-2025-21042 is an out-of-bounds write vulnerability in Samsung's proprietary libimagecodec.quram.so image-processing library. Insufficient bounds checking while parsing a specially crafted image permits attacker-controlled data to overwrite adjacent memory. The resulting memory corruption can enable arbitrary code execution in the context of the image-processing service or application. The issue affects Samsung Galaxy firmware prior to the April 2025 Security Maintenance Release 1 and was exploited as a zero-day to deliver LANDFALL spyware through malformed DNG images.
