Detailsinfo

A vulnerability has been found in Linux Kernel (Operating System) and classified as critical. This vulnerability affects an unknown code of the component Freescale Hypervisor Manager. The manipulation as part of a Parameter leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A flaw was found in the Linux kernel's freescale hypervisor manager implementation, kernel versions 5.0.x up to, excluding 5.0.17. A parameter passed to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the system, corrupt memory, or create other adverse security affects.

The weakness was disclosed 07/30/2019 as not defined bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability was named CVE-2019-10142 since 03/27/2019. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available.
