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.

Security readout for executives and security teams

This is an old Linux kernel flaw in the mpt2sas SCSI driver. A local user could send crafted ioctl input that may corrupt kernel memory, expose kernel memory, or potentially raise privileges. The business risk is mainly legacy systems with this driver and local account access. Exposure is most plausible on legacy Linux systems running kernel 2.6.38 or earlier with the mpt2sas driver present or reachable. Vendor advisories exist, but the source bundle does not provide a complete affected product matrix. Treat this as a legacy exposure cleanup item unless vulnerable systems still host sensitive workloads or allow many local users. Priority rises for shared servers, virtualization hosts, and unsupported appliances where kernel updates are difficult. Mitigation focus: Apply vendor kernel or platform updates that include the mpt2sas validation fix.; Review Red Hat, VMware, SUSE, Avaya, or relevant vendor advisories for affected versions.; Remove, disable, or restrict mpt2sas where it is unnecessary and operationally safe..
