Remote memory corruption via improper image validation
Published Nov 5, 2025 · Updated Nov 5, 2025
Out-of-bounds write in libimagecodec.quram.so on Samsung Mobile Devices with Android 13 through 16 allows remote attackers to corrupt memory. The image codec writes beyond its intended buffer because it does not properly validate untrusted image input; Samsung has not disclosed the affected parser path or field. The CNA assessment requires user interaction, and Samsung reports an out-of-bounds memory write rather than code execution or device compromise.
