Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.9.4

Description The issue allows local users to obtain sensitive information from kernel memory. This is achieved through either a crafted IDAGETPCIINFO command for a /dev/ida device, related to the ida locked ioctl function in drivers/block/cpqarray.c, or a crafted CCISS PASSTHRU32 command for a /dev/cciss device, related to the cciss ioctl32 passthru function in drivers/block/cciss.c.

Recommendations For Linux kernel versions prior to 3.9.4, update to version 3.9.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the /dev/ida and /dev/cciss devices to minimize the risk of exploitation.
