Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.17.3

Description: The issue is related to the improper validation of secs per zone in a corrupted f2fs image, which can lead to a divide-by-zero error. This can potentially allow an attacker to cause a denial of service.

Recommendations: For Linux kernel versions prior to 4.17.3, update to version 4.17.3 or later to resolve the issue. As a temporary workaround, consider restricting access to corrupted f2fs images to minimize the risk of exploitation.
