CVE-2017-7616 in Ubuntu

CVE-2017-7616

Priority

Description

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.

Ubuntu-Description

It was discovered that an information leak existed in the set_mempolicy and
mbind compat syscalls in the Linux kernel. A local attacker could use this
to expose sensitive information (kernel memory).
