CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2016-4565 – kernel: infiniband: Unprivileged process can overwrite kernel memory using rdma_ucm.ko
https://notcve.org/view.php?id=CVE-2016-4565
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3 incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface. La memoria de pila InfiniBand (también conocida como IB) en el kernel de Linux en versiones anteriores a 4.5.3 confía incorrectamente en llamadas al sistema de escritura, lo que permite a usuarios locales provocar una denegación de servicio (operación de escritura en la memoria del kernel) o posiblemente tener otro impacto no especificado a través de una interfaz uAPI. A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e6bd18f57aad1a2d1ef40e646d03ed0f2515c9e3 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-264: Permissions, Privileges, and Access Controls •

Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. Vulnerabilidad de uso después de liberación de memoria en drivers/net/ppp/ppp_generic.c en el kernel de Linux en versiones anteriores a 4.5.2 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída de sistema o spinlock) o posiblemente tener otro impacto no especificado eliminando una red namespace, relacionado con las funciones ppp_register_net_channel y ppp_unregister_channel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1f461dcdd296eecedaffffc6bae2bfa90bd7eb89 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org • CWE-416: Use After Free •

The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message. La función rtnl_fill_link_ifmap en net/core/rtnetlink.c en el kernel de Linux en versiones anteriores a 4.5.5 no inicializa una estructura de datos determinada, lo que permite a usuarios locales obtener información sensible del kernel de memoria de pila leyendo un mensaje Netlink. • https://www.exploit-db.com/exploits/46006 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5f8e44741f9f216e33736ea4ec65ca9ac03036e6 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The msr_mtrr_valid function in arch/x86/kvm/mtrr.c in the Linux kernel before 4.6.1 supports MSR 0x2f8, which allows guest OS users to read or write to the kvm_arch_vcpu data structure, and consequently obtain sensitive information or cause a denial of service (system crash), via a crafted ioctl call. La función msr_mtrr_valid en arch/x86/kvm/mtrr.c en el kernel de Linux en versiones anteriores a 4.6.1 sostiene MSR 0x2f8, lo que permite a usuarios invitados del sistema operativo leer o escribir en la estructura de datos kvm_arch_vcpu y, por lo tanto, obtener información sensible o provocar una denegación de servicio (caída de sistema), a través de una llamada ioctl manipulada. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9842df62004f366b9fed2423e24df10542ee0dc5 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.1 http://www.openwall.com/lists/oss-security/2016/05/16/2 https://bugzilla.redhat.com/show_bug.cgi?id=1332139 https://github.com/torvalds/linux/commit/9842df62004f366b9fed2423e24df10542ee0dc5 • CWE-284: Improper Access Control •
