  "summary": "selinux: reject a class permission count below its inherited common",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: reject a class permission count below its inherited common\n\nsecurity_get_permissions() maps an inherited common's permissions into\nan array sized by the class's own permissions.nprim, but class_read()\ntakes that nprim verbatim from the policy image and never checks that it\ncovers the common.  A class that inherits a common of N permissions while\ndeclaring a smaller nprim is accepted, and on load the common's\npermissions are written past the class-sized array -- an out-of-bounds\nheap write.\n\nReject a class whose permission count is below its inherited common's.\nWell-formed policies, where the class count already includes the\ninherited permissions, are unaffected.",
