CVSS: 5.5EPSS: 0%CPEs: 10EXPL: 1CVE-2018-10881 – kernel: out-of-bound access in ext4_get_group_info() when mounting and operating a crafted ext4 image
https://notcve.org/view.php?id=CVE-2018-10881
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image. Se ha detectado una vulnerabilidad en el sistema de archivos ext4 del kernel de Linux. Un usuario local puede provocar un acceso fuera de límites en la función ext4_get_group_info, una denegación de servicio (DoS) y un cierre inesperado del sistema montando y operando una imagen del sistema de archivos ext4 especialmente manipulada. • http://patchwork.ozlabs.org/patch/929792 http://www.securityfocus.com/bid/104901 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://bugzilla.kernel.org/show_bug.cgi?id=200015 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10881 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6e8ab72a812396996035a37e5ca4b3b99b5d214b https://lists.debian.org/debia • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-10901
A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.
