Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and earlier might allow local users to gain privileges or cause a denial of service (memory corruption) via an ioctl call specifying a crafted value that triggers a heap-based buffer overflow.

Security readout for executives and security teams

CVE-2011-1494 is a Linux kernel flaw in the mpt2sas storage driver. A local user could trigger memory corruption through a crafted ioctl request, potentially crashing the system or gaining higher privileges. The business risk is mainly for legacy Linux systems and products that still include affected kernels. Exposure is most likely on older Linux systems running kernel 2.6.38 or earlier with the mpt2sas driver available. Downstream vendor platforms referenced by advisories should be assessed through their own package and firmware guidance. Treat this as a legacy-infrastructure risk with high impact but local access requirements. Prioritize internet-facing, multi-user, virtualized, or shared administrative environments first, then close gaps through vendor kernel updates or retirement of unsupported systems. Mitigation focus: Inventory legacy Linux kernels at or before 2.6.38.; Check whether the mpt2sas driver is present or loaded.; Apply kernel updates from the operating system or appliance vendor..
