An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL ** EN DISPUTA ** Un problema fue encontrado en la función ip_ra_control en el archivo net/ipv4/ip_sockglue.c en el kernel de Linux hasta la versión 5.1.5. Hay un kmalloc sin marcar de new_ra, que podría permitir a un atacante generar una Denegación de Servicio (desreferencia de puntero NULL y bloqueo del sistema).

**DISPUTED** An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5. phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE: This id is disputed as not being an issue because “All the code touched by the referenced commit runs only at boot, before any user processes are started. Therefore, there is no possibility for an unprivileged user to control it.”. ** EN DISPUTA ** Se descubrió un problema en el subsistema efi en el kernel de Linux hasta la versión 5.1.5. phys_efi_set_virtual_address_map en arch / x86 / platform / efi / efi.c y efi_call_phys_prolog en arch / x86 / platform / efi / efi_64.c manejan mal los errores de asignación de memoria. NOTA: Esta identificación se disputa por no ser un problema porque “Todo el código tocado por el commit referenciado solo se ejecuta en el arranque, antes de que se inicien los procesos del usuario.

CVSS: 6.2EPSS: 0%CPEs: 1EXPL: 1CVE-2018-7191 – kernel: denial of service via ioctl call in network tun handling
https://notcve.org/view.php?id=CVE-2018-7191
In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343. En el subsistema tun en el kernel de Linux anterior a 4.13.14, dev_get_valid_name no es llamada antes de register_netdevice. Esto permite que los usuarios locales causen una denegación de servicio (NULL pointer dereference and panic) por medio de una llamada ioctl (TUNSETIFF) con un nombre de desarrollo que contiene un carácter /. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://www.securityfocus.com/bid/108380 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743792 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1748846 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.13.14 https://git.kernel.org/cgit • CWE-476: NULL Pointer Dereference •
