A flaw was found in the Linux kernels handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory.

Weakness

A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.
