CVE-2016-10208

MEDIUM

Linux Kernel < 4.9.8 - Out-of-Bounds Read

Title source: rule

Description

The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image.
