Description

A vulnerability was found in the ext4 filesystem driver in the Linux kernel. This flaw occurs when the system processes a maliciously crafted or corrupted ext4 filesystem image, as the driver fails to properly validate its structural data. A local user with the ability to mount such an image could use this flaw to cause a system crash, resulting in a denial of service. This vulnerability could also lead to silent corruption of data on the affected filesystem.
