Integer signedness error in the pmcraid_ioctl_passthrough function in drivers/scsi/pmcraid.c in the Linux kernel before 3.1 might allow local users to cause a denial of service (memory consumption or memory corruption) via a negative size value in an ioctl call. NOTE: this may be a vulnerability only in unusual environments that provide a privileged program for obtaining the required file descriptor.

Security readout for executives and security teams

CVE-2011-2906 is an old Linux kernel issue in the pmcraid SCSI driver. A local user may be able to trigger excessive memory use or memory corruption through a malformed ioctl size value. Business urgency is usually limited unless affected kernels and exposed pmcraid access exist. Likely exposure is narrow: systems running Linux kernels before 3.1 or vendor kernels without the fix, with the pmcraid driver relevant, and local users able to reach the required ioctl path. The CVE source explicitly cautions this may only matter in unusual environments. Treat as a targeted legacy kernel hygiene item, not an internet-wide emergency. Prioritize only systems with affected kernels, local untrusted users, and pmcraid exposure. Routine kernel patch management should address most risk. Mitigation focus: Upgrade to Linux 3.1 or a vendor-supported kernel containing the fix.; Check vendor kernel advisories for backported CVE-2011-2906 fixes.; Restrict local access to programs exposing pmcraid file descriptors..
