See how udisks project compares to other vendors in security performance
A vulnerability found in udisks2. This flaw allows an attacker to input a specially crafted image file/USB leading to kernel panic. The highest threat from this vulnerability is to system availability.
Sebastian Krahmer reported that the udisks service (via D-BUS) could be used to load arbitrary Linux kernel modules. Since "mount -t $NAME" is called, this also triggers a "modprobe -q -- $NAME" which will load the Linux kernel module from /lib/modules/.
The upstream bug report is: https://bugs.freedesktop.org/showbug.cgi?id=32232 and no upstream fix has been made as of yet, although the upstream bug report has a few suggestions on how to correct this.
