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 •

Firejail before 0.9.44.4, when running on a Linux kernel before 4.8, allows context-dependent attackers to bypass a seccomp-based sandbox protection mechanism via the --allow-debuggers argument.

CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2016-10147 – kernel: Kernel crash by spawning mcrypt(alg) with incompatible algorithm
https://notcve.org/view.php?id=CVE-2016-10147
crypto/mcryptd.c in the Linux kernel before 4.8.15 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5). crypto/mcryptd.c en el kernel de Linux en versiones anteriores a 4.8.15 permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída del sistema) usando un socket AF_ALG con un algoritmo incompatible, según lo demostrado por mcryptd(md5). Algorithms not compatible with mcryptd could be spawned by mcryptd with a direct crypto_alloc_tfm invocation using a "mcryptd(alg)" name construct. This causes mcryptd to crash the kernel if an arbitrary "alg" is incompatible and not intended to be used with mcryptd. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=48a992727d82cb7db076fa15d372178743b1f4cd http://marc.info/?l=linux-crypto-vger&m=148063683310477&w=2 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.15 http://www.openwall.com/lists/oss-security/2017/01/17/13 http://www.securityfocus.com/bid/95677 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://bugzilla.redhat.com/show_bug.cgi?id&# • CWE-476: NULL Pointer Dereference •
