| Description: | The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call. It was discovered that an information leak existed in __get_user_asm_ex() in the Linux kernel. A local attacker could use this to expose sensitive information.
