category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA72DZ
CVE: CVE-2022-48738

--------------------------------

commit 9bdd10d5 upstream.

While the $val/$val2 values passed in from userspace are always >= 0
integers, the limits of the control can be signed integers and the $min
can be non-zero and less than zero. To correctly validate $val/$val2
against platform_max, add the $min offset to val first.
