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.

CVSS: 8.3EPSS: 0%CPEs: 20EXPL: 0CVE-2018-14633 – kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target
https://notcve.org/view.php?id=CVE-2018-14633
A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. • http://www.securityfocus.com/bid/105388 https://access.redhat.com/errata/RHSA-2018:3651 https://access.redhat.com/errata/RHSA-2018:3666 https://access.redhat.com/errata/RHSA-2019:1946 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14633 https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/commit/?h=4.19/scsi-fixes&id=1816494330a83f2a064499d8ed2797045641f92c https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/commit/?h=4.19/scsi-fixes&id=8c39e2699 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
