Problem Description:

+

Handlers for *_CFG_PAGE read / write ioctls in the mpr, mps, and + mpt drivers allocated a buffer of a caller-specified size, but + copied to it a fixed size header. Other heap content would be + overwritten if the specified size was too small.

+

Impact:

+

Users with access to the mpr, mps or mpt device node may overwrite + heap data, potentially resulting in privilege escalation. Note that + the device node is only accessible to root and members of the operator + group.
