7.1

Alta

VetorAV:N/AC:M/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions: Linux kernel versions through 4.17.10
Description: The issue is related to the remove dirty segment() function in the Linux kernel, which is associated with a null pointer dereference. Exploitation of this issue may allow an attacker to cause a denial of service. There is an out-of-bounds access in the remove dirty segment() function in fs/f2fs/segment.c when mounting an f2fs image.
Recommendations: For Linux kernel versions through 4.17.10, consider updating to a newer version to resolve the issue. As a temporary workaround, restrict access to the remove dirty segment() function in fs/f2fs/segment.c to minimize the risk of exploitation. Avoid mounting untrusted f2fs images until the issue is resolved.
