kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 30955111. kernel/events/core.c en el subsistema de rendimiento en el kernel de Linux en versiones anteriores a 4.0 no gestiona adecuadamente bloqueos durante ciertas migraciones, lo que permite a usuarios locales obtener privilegios a través de una aplicación manipulada, vulnerabilidad también conocida como error interno 30955111. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f63a8daa5812afef4f06c962351687e1ff9ccb2b http://source.android.com/security/bulletin/2016-12-01.html http://www.debian.org/security/2017/dsa-3791 http://www.securityfocus.com/bid/94679 https://bugzilla.redhat.com/show_bug.cgi?id=1403842 https://github.com/torvalds/linux/commit/f63a8daa5812afef4f06c962351687e1ff9ccb2b • CWE-264: Permissions, Privileges, and Access Controls •
CVSS: 4.7EPSS: 0%CPEs: 1EXPL: 0CVE-2016-6213 – kernel: Overflowing kernel mount table using shared bind mount
https://notcve.org/view.php?id=CVE-2016-6213
fs/namespace.c in the Linux kernel before 4.9 does not restrict how many mounts may exist in a mount namespace, which allows local users to cause a denial of service (memory consumption and deadlock) via MS_BIND mount system calls, as demonstrated by a loop that triggers exponential growth in the number of mounts. fs/namespace.c en el kernel de Linux en versiones anteriores a 4.9 no restringe la cantidad de montajes que pueden existir en un espacio de nombre del montaje, lo que permite a usuarios locales provocar una denegación de servicio (consumo de memoria y punto muerto) a través de llamadas al sistema de montaje MS_BIND, según lo demostrado por un bucle que desencadena un crecimiento exponencial en el número de montajes. It was found that in Linux kernel the mount table expands by a power-of-two with each bind mount command. If a system is configured to allow non-privileged user to do bind mounts, or allows to do so in a container or unprivileged mount namespace, then non-privileged user is able to cause a local DoS by overflowing the mount table, which causes a deadlock for the whole system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d29216842a85c7970c536108e093963f02714498 http://www.openwall.com/lists/oss-security/2016/07/13/8 http://www.securityfocus.com/bid/91754 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://bugzilla.redhat.com/show_bug.cgi?id=1356471 https://github.com/torvalds/linux/commit/d29216842a85c7970c536108e093963f02714498 https://access.redhat.com/security/cve/CVE-2016-6213 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
