CVE-2025-58478Network attack vector

Memory corruption via ignored DNG PixelType

Published Dec 2, 2025 · Updated Dec 2, 2025

Out-of-bounds write in libimagecodec.quram.so on Samsung Mobile Devices before SMR Dec-2025 Release 1 allows remote attackers to corrupt memory. QuramDng opcode handlers ignore the image PixelType, so they process pixel data with an incompatible representation and write beyond the destination buffer. A remote attacker needs no privileges but must persuade a user to process a crafted DNG image; the published impact is memory corruption, not code execution.
