How the CVE Works:
This vulnerability resides in the libimagecodec.quram.so library, which is responsible for processing various image formats on Samsung devices. The flaw is an out-of-bounds write that occurs when the library parses a specially crafted image file. An attacker can create a malicious image designed to trigger an incorrect memory allocation or an unbounded memory copy operation. When a victim is tricked into opening this image in a vulnerable application, the library fails to properly validate the image dimensions or data chunk sizes. This allows the attacker to write data beyond the boundaries of the allocated heap buffer, corrupting adjacent memory. By carefully crafting the overwritten data, a remote attacker can achieve arbitrary code execution with the privileges of the application using the library, potentially compromising the entire device.
