Description Agostino Sarubbo gentoo-dev 2013-11-25 19:53:46 UTC
From ${URL} :

Linux kernel built with the Adaptec RAID controller support(CONFIG_SCSI_AACRAID)
along with the compat mode(CONFIG_COMPAT), is vulnerable due to a missing
capability check in a compat ioctl routine. This could lead to undue usage of
restricted operations by users.

A user/program could use this flaw to perform protected operations via compat
ioctl route.

Upstream fix:
