Severity ?
4.3 (Medium) - CVSS:3.0/AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
