The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba. La funcionalidad mbcache en las implementaciones del sistema de archivos ext2 y ext4 en el kernel de Linux en versiones anteriores a 4.6 no maneja adecuadamente bloque de almacenamiento en caché xattr, lo que permite a usuarios locales provocar una denegación de servicio (bloqueo débil) a través de operaciones de sistema de archivos en entornos que usan muchos atributos, como se demuestra por Ceph y Samba. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=82939d7999dfc1f1998c4b1c12e2f19edbdff272 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=be0726d33cb8f411945884664924bed3cb8c70ee http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f9a61eb4e2471c56a63cd804c7474128138c38ac http://www.openwall.com/lists/oss-security/2016/08/22/2 http://www.openwall.com/lists/oss-security/2016/08/25/4 https://bugzilla.kernel.org/show_bug.cgi?id=10 • CWE-19: Data Processing Errors •

https://notcve.org/view.php?id=CVE-2016-7117
Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel before 4.5.2 allows remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing. Vulnerabilidad de uso después de liberación de memoria en la función the __sys_recvmmsg en net/socket.c en el kernel de Linux en versiones anteriores a 4.5.2 permite a atacantes remotos ejecutar código arbitrario a través de vectores que involucran una llamada al sistema recvmmsg que no es manejada correctamente durante el procesamiento del error. A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=34b88a68f26a75e4fded796f1a49c40f82234b7d http://rhn.redhat.com/errata/RHSA-2016-2962.html http://rhn.redhat.com/errata/RHSA-2017-0031.html http://rhn.redhat.com/errata/RHSA-2017-0036.html http://rhn.redhat.com/errata/RHSA-2017-0065.html http://rhn.redhat.com/errata/RHSA-2017-0086.html http://rhn.redhat.com/errata/RHSA-2017-0091.html http://rhn.redhat.com/errata/RHSA-2017-0113.html http://rhn. • CWE-19: Data Processing Errors CWE-416: Use After Free •
