kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allows local users to obtain potentially sensitive address information, aka a "pointer leak." kernel/bpf/verifier.c en el kernel de Linux hasta la versión 4.14.8 gestiona de manera incorrecta las comparaciones states_equal entre el tipo de datos del puntero y el tipo de datos UNKNOWN_VALUE, lo que permite que usuarios locales obtengan información de direcciones sensible. Esto también se conoce como "pointer leak". • http://www.securityfocus.com/bid/102320 http://www.securitytracker.com/id/1040059 https://anonscm.debian.org/cgit/kernel/linux.git/commit/?h=stretch-security&id=ad775f6ff7eebb93eedc2f592bc974260e7757b0 https://anonscm.debian.org/cgit/kernel/linux.git/tree/debian/patches/bugfix/all/bpf-verifier-fix-states_equal-comparison-of-pointer-and-unknown.patch?h=stretch-security https://usn.ubuntu.com/usn/usn-3523-2 https://www.debian.org/security/2017/dsa-4073 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device. La función usb_destroy_configuration en drivers/usb/core/config.c en el subsistema del núcleo USB en el kernel de Linux hasta la versión 4.14.5 no considera el máximo número de configuraciones e interfaces antes de intentar liberar recursos. Esto permite que usuarios locales provoquen una denegación de servicio (acceso de escritura fuera de límites) o, posiblemente, tengan otro tipo de impacto sin especificar mediante un dispositivo USB manipulado.

The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state. La función dccp_disconnect en net/dccp/proto.c en el kernel de Linux hasta la versión 4.14.3 permite que usuarios locales obtengan privilegios o provoquen una denegación de servicio (uso de memoria previamente liberada) mediante una llamada del sistema de conexión AF_UNSPEC durante el estado DCCP_LISTEN. A use-after-free vulnerability was found in DCCP socket code affecting the Linux kernel since 2.6.16. This vulnerability could allow an attacker to their escalate privileges. The Linux kernel suffers from a DCCP socket use-after-free vulnerability. • https://www.exploit-db.com/exploits/43234 http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://lists.openwall.net/netdev/2017/12/04/224 http://www.openwall.com/lists/oss-security/2017/12/05/1 http://www.securityfocus.com/bid/102056 https://access.redhat.com/errata/RHSA-2018:0399 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2018:1130 https://acces • CWE-416: Use After Free •

The rngapi_reset function in crypto/rng.c in the Linux kernel before 4.2 allows attackers to cause a denial of service (NULL pointer dereference). La función rngapi_reset en crypto/rng.c en el kernel de Linux en versiones anteriores a la 4.2 permite que atacantes provoquen una denegación de servicio (desreferencia de puntero NULL). A flaw was found in the Linux kernel's random number generator API. A null pointer dereference in the rngapi_reset function may result in denial of service, crashing the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=94f1bb15bed84ad6c893916b7e7b9db6f1d7eec6 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://bugzilla.redhat.com/show_bug.cgi?id=1485815 https://bugzilla.redhat.com/show_bug.cgi?id=1514609 https://github.com/torvalds/linux/commit/94f1bb15bed84ad6c893916b7e7b9db6f1d7eec6 https://access.redhat.com/security/cve/CVE-2017-15116 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •
