A missing address check in the callers of the show_opcodes() in the Linux kernel allows an attacker to dump the kernel memory at an arbitrary kernel address into the dmesg log. La falta de una comprobación de direcciones en los llamantes de show_opcodes() en el kernel de Linux permite que un atacante vuelque la memoria del kernel en una dirección arbitraria del kernel en el registro dmesg. • http://www.securitytracker.com/id/1041804 https://bugs.chromium.org/p/project-zero/issues/detail?id=1650 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14656 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=342db04ae71273322f0011384a9ed414df8bdae4 https://lore.kernel.org/lkml/20180828154901.112726-1-jannh%40google.com/T https://seclists.org/oss-sec/2018/q4/9 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-17977
The Linux kernel 4.14.67 mishandles certain interaction among XFRM Netlink messages, IPPROTO_AH packets, and IPPROTO_IP packets, which allows local users to cause a denial of service (memory consumption and system hang) by leveraging root access to execute crafted applications, as demonstrated on CentOS 7. El kernel de Linux en su versión 4.14.67 gestiona incorrectamente ciertas interacciones entre los mensajes XFRM Netlink, los paquetes IPPROTO_AH y los paquetes IPPROTO_IP, lo que permite que los usuarios locales provoquen una denegación de servicio (consumo de memoria y bloqueo del sistema) aprovechando el acceso root para ejecutar aplicaciones manipuladas, tal y como queda demostrado en CentOS 7. • http://www.securityfocus.com/bid/105539 https://www.openwall.com/lists/oss-security/2018/10/05/5 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.1EPSS: 0%CPEs: 4EXPL: 0CVE-2018-18021 – kernel: Privilege escalation on arm64 via KVM hypervisor
https://notcve.org/view.php?id=CVE-2018-18021
arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes. arch/arm64/kvm/guest.c en KVM en el kernel de Linux en versiones anteriores a la 4.18.12 en la plataforma arm64 gestiona de manera incorrecta la llamada IOCTL KVM_SET_ON_REG. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2a3f93459d689d990b3ecfbe782fec89b97d3279 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d26c25a9d19b5976b319af528886f89cf455692d http://www.securityfocus.com/bid/105550 https://access.redhat.com/errata/RHSA-2018:3656 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.18.12 https://github.com/torvalds/linux/commit/2a3f93459d689d990b3ecfbe782fec89b97d3279 https://github.com/torvalds/linux/commit/d26c25a9d19b5 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-17972
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. Se descubrió un problema en la función proc_pid_stack en fs/proc/base.c en el kernel de Linux hasta la versión 4.18.11. No asegura que solo root pueda inspeccionar la pila del kernel de una tarea arbitraria, lo que permite que un atacante local explote de forma arbitraria el proceso de marcha atrás en la pila a la hora de producirse una excepción (stack unwinding) y filtre el contenido de la pila de tareas del kernel.
