CVE-2011-1495

Published: 3 May 2011

drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and earlier does not validate (1) length and (2) offset values before performing memory copy operations, which might allow local users to gain privileges, cause a denial of service (memory corruption), or obtain sensitive information from kernel memory via a crafted ioctl call, related to the _ctl_do_mpt_command and _ctl_diag_read_buffer functions.

From the Ubuntu Security Team

Dan Rosenberg discovered that MPT devices did not correctly validate certain values in ioctl calls. If these drivers were loaded, a local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy.
