CVSS: 6.2EPSS: 0%CPEs: 1EXPL: 0CVE-2016-10208 – kernel: EXT4 memory corruption / SLAB out-of-bounds read
https://notcve.org/view.php?id=CVE-2016-10208
The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image. La función ext4_fill_super en fs/ext4/super.c en el kernel de Linux hasta la versión 4.9.8 no valida correctamente los grupos de bloque meta, lo que permite a atacantes físicamente próximos provocar una denegación de servicio (lectura fuera de límites y caída del sistema) a través de una imagen ext4 manipulada. Mounting a crafted EXT4 image read-only leads to an attacker controlled memory corruption and SLAB-Out-of-Bounds reads. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3a4b77cd47bb837b8557595ec7425f281f2ca1fe http://seclists.org/fulldisclosure/2016/Nov/75 http://www.openwall.com/lists/oss-security/2017/02/05/3 http://www.securityfocus.com/bid/94354 https://access.redhat.com/errata/RHSA-2017:1297 https://access.redhat.com/errata/RHSA-2017:1298 https://access.redhat.com/errata/RHSA-2017:1308 https://bugzilla.redhat.com/show_bug.cgi?id=1395190 https://github.com/torvalds&# • CWE-125: Out-of-bounds Read •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2017-2596 – Kernel: kvm: page reference leakage in handle_vmon
https://notcve.org/view.php?id=CVE-2017-2596
The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references. La función nested_vmx_check_vmptr en arch/x86/kvm/vmx.c en el kernel de Linux hasta la versión 4.9.8 emula indebidamente la instrucción VMXON, lo que permite a usuarios del SO invitado KVM L1 provocar una denegación de servicio (consumo de memoria del SO anfitrión) aprovechando el manejo incorrecto de referencia de páginas. Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to host memory leakage issue. It could occur while emulating VMXON instruction in 'handle_vmon'. An L1 guest user could use this flaw to leak host memory potentially resulting in DoS. • http://www.debian.org/security/2017/dsa-3791 http://www.openwall.com/lists/oss-security/2017/01/31/4 http://www.securityfocus.com/bid/95878 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://bugzilla.redhat.com/show_bug.cgi?id=1417812 https://access.redhat.com/security/cve/CVE-2017-2596 • CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2017-2583
The load_segment_descriptor implementation in arch/x86/kvm/emulate.c in the Linux kernel before 4.9.5 improperly emulates a "MOV SS, NULL selector" instruction, which allows guest OS users to cause a denial of service (guest OS crash) or gain guest OS privileges via a crafted application. La implementación de load_segment_descriptor en arc/x86/kvm/emulate.c en el kernel de Linux en versiones anteriores a 4.9.5 emula indebidamente una instrucción "MOV SS, NULL selector", lo que permite a usuarios del SO invitado provocar una denegación de servicio (caída del SO invitado) u obteniendo privilegios de SO invitado a través de una aplicación manipulada. Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support was vulnerable to an incorrect segment selector(SS) value error. The error could occur while loading values into the SS register in long mode. A user or process inside a guest could use this flaw to crash the guest, resulting in DoS or potentially escalate their privileges inside the guest. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=33ab91103b3415e12457e3104f0e4517ce12d0f3 http://www.debian.org/security/2017/dsa-3791 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.5 http://www.openwall.com/lists/oss-security/2017/01/19/2 http://www.securityfocus.com/bid/95673 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://bugzilla.redhat.com/show_bug.cgi?id=1414735 https:/ • CWE-250: Execution with Unnecessary Privileges •
