Linux Kernel Keyctl Null Pointer Dereference
Posted Nov 15, 2016
Authored by Ralf Spenneberg, Hendrik Schwartke, Sergej Schumilo

A malicious interaction with the keyctl usermode interface allows an attacker to crash the kernel. Processing the attached certificate by the kernel leads to a kernel nullpointer dereference. This vulnerably can be triggered by any unprivileged user locally.

Linux Kernel EXT4 Memory Corruption / SLAB Out-Of-Bounds Read
Posted Nov 15, 2016
Authored by Ralf Spenneberg, Sergej Schumilo

Mounting a crafted EXT4 image read-only leads to a memory corruption and SLAB out of bounds reads (according to KASAN). Since the mounting procedure is a privileged operation, an attacker is probably not able to trigger this vulnerability on the commandline. Instead the automatic mounting feature of the GUI via a crafted USB device is required.

Linux Kernel EXT4 Error Handling Denial Of Service

Mounting a crafted EXT4 image as read-only leads to a kernel panic. Since the mounting procedure is a privileged operation, an attacker is probably not able to trigger this vulnerability on the commandline. Instead the automatic mounting feature of the GUI via a crafted USB-device is required.
