CVSS: 8.8EPSS: 0%CPEs: 60EXPL: 0CVE-2019-14821 – Kernel: KVM: OOB memory access via mmio ring buffer
https://notcve.org/view.php?id=CVE-2019-14821
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. Se encontró un problema de acceso fuera de límites en el kernel de Linux, todas las versiones hasta 5.3, en la manera en que el hipervisor KVM del kernel de Linux implementa la operación de escritura MMIO Coalesced. Opera en un objeto MMIO ring buffer "struct kvm_coalesced_mmio", en donde los índices de escritura "ring-)first" y "ring-)last" podrían ser suministrados por un proceso de espacio de usuario del host. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/09/20/1 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517&# • CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 0%CPEs: 82EXPL: 1CVE-2019-14835 – kernel: vhost-net: guest to host kernel escape during migration
https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.
