Описание
Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel through 4.10.9 allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation.
Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in 'mm/mempolicy.c' in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation.
Отчет
This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 on ppc64 and ppc64le platforms. This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/. This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 6 and 7 on ppc64 and ppc64le platforms. Future Linux kernel updates for the respective releases might address this issue. Only ppc64 and ppc64le hardware platforms are vulnerable. The Linux kernel packages for other platforms which Red Hat ships (i386, x86_64, s390x) are not vulnerable to this security flaw. This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux MRG-2 as this product is shipped for x86_64 hardware platform only.
