CVE-2018-14678
https://notcve.org/view.php?id=CVE-2018-14678
An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. The xen_failsafe_callback entry point in arch/x86/entry/entry_64.S does not properly maintain RBX, which allows local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.17.11, tal y como se utiliza en Xen hasta las versiones 4.11.x. El punto de entrada de xen_failsafe_callback en arch/x86/entry/entry_64.S no mantiene correctamente el RBX, lo que permite a los usuarios locales provocar una denegación de servicio (uso de memoria no inicializada y cierre inesperado del sistema). • http://www.securityfocus.com/bid/104924 http://www.securitytracker.com/id/1041397 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3931-1 https://usn.ubuntu.com/3931-2 https://www.debian.org/security/2018/dsa-4308 https://xenbits.xen.org/xsa/advisory-274.html • CWE-665: Improper Initialization •
