CVSS: 7.5EPSS: 0%CPEs: 7EXPL: 0CVE-2016-2117 – kernel: Kernel memory leakage to ethernet frames due to buffer overflow in ethernet drivers
https://notcve.org/view.php?id=CVE-2016-2117
The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data. La función atl2_probe en drivers/net/ethernet/atheros/atlx/atl2.c en el kernel de Linux hasta la versión 4.5.2 activa incorrectamente scatter/gather I/O, lo que permite a atacantes remotos obtener información sensible de la memoria del kernel leyendo datos de paquete. It was discovered that the atl2_probe() function in the Atheros L2 Ethernet driver in the Linux kernel incorrectly enabled scatter/gather I/O. A remote attacker could use this flaw to obtain potentially sensitive information from the kernel memory. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f43bfaeddc79effbf3d0fcb53ca477cca66f3db8 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3607 http://www.openwall.com/lists/oss-security/2016/03/16/7 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.secu • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The fpu_fxrstor function in arch/x86/i387.c in Xen 4.x does not properly handle writes to the hardware FSW.ES bit when running on AMD64 processors, which allows local guest OS users to obtain sensitive register content information from another guest by leveraging pending exception and mask bits. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-2076. La función fpu_fxrstor en arch/x86/i387.c en Xen 4.x no maneja correctamente escrituras al bit FSW.ES hardware cuando se ejecuta en procesadores AMD64, lo que permite a usuarios locales del SO invitado obtener información sensible del contenido de registro de otro invitado aprovechando una excepción pendiente y bits de máscara.
