28 Jul 2018 — 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 la... • http://www.securityfocus.com/bid/104924 • CWE-665: Improper Initialization •
