CVE-2017-14140
Publication date 5 September 2017
Last updated 24 July 2024
Ubuntu priority
Cvss 3 Severity Score
The move_pages system call in mm/migrate.c in the Linux kernel before 4.12.9 doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR.
From the Ubuntu Security Team
Otto Ebeling discovered that the memory manager in the Linux kernel did not properly check the effective UID in some situations. A local attacker could use this to expose sensitive information.
