CVE-2016-3695 (CCN-136942)

Assigned:2016-03-30
Published:2016-03-30
Updated:2018-01-10
Summary:The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set.
