Memory corruption on boot with UEFI

This document (7018028) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 12 Service Pack 1 (SLES 12 SP1)


A memory corruption issue affecting systems that use UEFI to boot
was discovered in the SUSE Linux Enterprise 12 SP1 kernel.

The function init_hibernation_keys(), which is executed exclusively
at boot time, erroneously freed a block of memory that had been
unreserved earlier and could be already re-allocated to store data
such as the initial system ram disk. In some circumstances this
could lead to a boot failure.


Users are advised to update to the latest kernel maintenance update
released for SLE 12 SP1. Version 3.12.62-60.62.1 and newer already
include the fix for this issue
