CVE-2017-7616
Published: 10 April 2017
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.
From the Ubuntu Security Team
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).
