The xsave/xrstor implementation in arch/x86/include/asm/xsave.h in the Linux kernel before 3.19.2 creates certain .altinstr_replacement pointers and consequently does not provide any protection against instruction faulting, which allows local users to cause a denial of service (panic) by triggering a fault, as demonstrated by an unaligned memory operand or a non-canonical address memory operand. La implementación de xsave/xrstor en arch/x86/include/asm/xsave.h en el kernel de Linux en versiones anteriores a 3.19.2 crea determinados punteros .altinstr_replacement y consecuentemente no provee ninguna protección contra fallo de instrucciones, lo que permite a usuarios locales provocar una denegación de servicio (pánico) desencadenando un fallo, según lo demostrado por un operando de memoria no alineada o un operando de dirección de memoria no canónico. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=06c8173eb92bbfc03a0fe8bb64315857d0badd06 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.19.2 http://www.openwall.com/lists/oss-security/2015/03/22/1 https://bugzilla.redhat.com/show_bug.cgi?id=1204729 https://github.com/torvalds/linux/commit/06c8173eb92bbfc03a0fe8bb64315857d0badd06 • CWE-20: Improper Input Validation •

The netlink_sendmsg function in net/netlink/af_netlink.c in the Linux kernel before 3.5.5 does not validate the dst_pid field, which allows local users to have an unspecified impact by spoofing Netlink messages. La función netlink_sendmsg en net/netlink/af_netlink.c en el kernel de Linux en versiones anteriores a 3.5.5 no valida el campo dst_pid, lo que permite a usuarios locales tener un impacto no especificado suplantando mensajes Netlink. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=20e1db19db5d6b9e4e83021595eab0dc8f107bef http://marc.info/?l=linux-netdev&m=134522422125983&w=2 http://marc.info/?l=linux-netdev&m=134522422925986&w=2 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.5.5 http://www.openwall.com/lists/oss-security/2015/02/22/10 http://www.securityfocus.com/bid/72739 https://bugzilla.redhat.com/show_bug.cgi?id=848949 https://github.com/torvalds/linux/com • CWE-284: Improper Access Control •

The fs_pin implementation in the Linux kernel before 4.0.5 does not ensure the internal consistency of a certain list data structure, which allows local users to cause a denial of service (system crash) by leveraging user-namespace root access for an MNT_DETACH umount2 system call, related to fs/fs_pin.c and include/linux/fs_pin.h. La implementación de fs_pin en el kernel de Linux en versiones anteriores a 4.0.5 no asegura la consistencia interna de una determinada estructura de datos de lista, lo que permite a usuarios locales provocar una denegación de servicio (caída de sistema) aprovechando acceso root al espacio de nombres de usuario para una llamada de sistema MNT_DETACH umount2, relacionado con fs/fs_pin.c y include/linux/fs_pin.h. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=820f9f147dcce2602eefd9b575bbbd9ea14f0953 http://openwall.com/lists/oss-security/2015/05/29/10 http://openwall.com/lists/oss-security/2015/05/29/5 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.5 http://www.openwall.com/lists/oss-security/2015/06/04/5 https://bugzilla.redhat.com/show_bug.cgi?id=1249849 https://github.com/torvalds/linux/commit/820f9f147dcce2602eefd9b575bbbd9ea14f0953 •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2012-6701 – kernel: AIO interface didn't use rw_verify_area() for checking mandatory locking on files and size of access
https://notcve.org/view.php?id=CVE-2012-6701
Integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. Desbordamiento de entero en fs/aio.c en el kernel de Linux en versiones anteriores a 3.4.1 permite a usuarios locales provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de un iovec AIO grande. It was found that AIO interface didn't use the proper rw_verify_area() helper function with extended functionality, for example, mandatory locking on the file. Also rw_verify_area() makes extended checks, for example, that the size of the access doesn't cause overflow of the provided offset limits. This integer overflow in fs/aio.c in the Linux kernel before 3.4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a70b52ec1aaeaf60f4739edb1b422827cb6f3893 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.4.1 http://www.openwall.com/lists/oss-security/2016/03/02/9 https://access.redhat.com/errata/RHSA-2018:1854 https://bugzilla.redhat.com/show_bug.cgi?id=1314288 https://github.com/torvalds/linux/commit/a70b52ec1aaeaf60f4739edb1b422827cb6f3893 https://access.redhat.com/security/cve/CVE-2012-6701 • CWE-190: Integer Overflow or Wraparound •
