The issue arises due to a NULL pointer dereference when processing a malformed JPEG file, which leads to a segmentation fault but does not introduce memory corruption or arbitrary code execution risks. Additionally, most applications using libjpeg-turbo process images in a non-privileged context, meaning a crash does not compromise system security beyond affecting availability. Since the exploitation requires user interaction (i.e., opening a crafted JPEG), and modern systems can handle such crashes gracefully (e.g., automatic process restart mechanisms), the overall impact remains low.", "threat_severity": "Low"}
