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.

CVE-2016-10208 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel
did not properly validate meta block groups. An attacker with physical
access could use this to specially craft an ext4 image that causes a denial
of service (system crash). (CVE-2016-10208)
It was discovered that an information disclosure vulnerability existed in
the ACPI implementation of the Linux kernel. A local attacker could use
this to expose sensitive information (kernel memory addresses).
(CVE-2017-11472)
It was discovered that a buffer overflow existed in the ACPI table parsing
implementation in the Linux kernel. A local attacker could use this to
construct a malicious ACPI table that, when loaded, cau

CVE-2016-10208 [MEDIUM] CWE-125 kernel: EXT4 memory corruption / SLAB out-of-bounds read
kernel: EXT4 memory corruption / SLAB out-of-bounds read
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.
Mounting a crafted EXT4 image read-only leads to an attacker controlled memory corruption and SLAB-Out-of-Bounds reads.
Statement: This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7, MRG-2 and realtime kernels. This has been rated as having Moderate security impact and is currently planned to be addressed in future updates.
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 and 6.

CVE-2016-10208 kernel: EXT4 memory corruption / SLAB out-of-bounds read
Mounting a crafted EXT4 image read-only leads to a memory corruption and SLAB-Out-of-Bounds Reads (according to KASAN). Automounting a disk image either as USB or loopback is not configured by default on servers but is enabled on desktop environments.
Attackers with a remote connection will likely be unable to trigger this vulnerability on the commandline. Instead the automatic mounting feature of the GUI via a crafted USB-device is required.
The system will likely panic with a page fault, but attackers may be able to map another page in the correct location and be able to overwrite or corrupt memory possibly leading to privilege escalation.
