CVSS: 4.9EPSS: 0%CPEs: 1EXPL: 0CVE-2015-8324 – kernel: Null pointer dereference when mounting ext4
https://notcve.org/view.php?id=CVE-2015-8324
The ext4 implementation in the Linux kernel before 2.6.34 does not properly track the initialization of certain data structures, which allows physically proximate attackers to cause a denial of service (NULL pointer dereference and panic) via a crafted USB device, related to the ext4_fill_super function. La implementación de ext4 en el kernel de Linux en versiones anteriores a 2.6.34 no rastrea correctamente la inicalización de determinadas estructuras de datos, lo que permite a atacantes físicamente próximos provocar una denegación de servicio (referencia a puntero NULL y pánico) a través de un dispositivo USB manipulado, relacionado con la función ext4_fill_super. A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images. An attacker with physical access to the system could use this flaw to crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=744692dc059845b2a3022119871846e74d4f6e11 http://mirror.linux.org.au/linux/kernel/v2.6/ChangeLog-2.6.34 http://rhn.redhat.com/errata/RHSA-2016-0855.html http://www.openwall.com/lists/oss-security/2015/11/23/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html https://bugzilla.redhat.com/show_bug.cgi?id=1267261 https://github.com/torvalds/linux/commit/744692dc059845b2a3022119871846e74d4f6e11 https • CWE-476: NULL Pointer Dereference •

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 •

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.

https://notcve.org/view.php?id=CVE-2016-2053
The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c. La función asn1_ber_decoder en lib/asn1_decoder.c en el kernel de Linux en versiones anteriores a 4.3 permite a atacantes provocar una denegación de servicio (pánico) a través de un archivo ASN.1 BER que carece de clave pública, llevando a un manejo incorrecto por la función public_key_verify_signature en crypto/asymmetric_keys/public_key.c. A syntax vulnerability was discovered in the kernel's ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUG_ON() in the public_key_verify_signature() function (crypto/asymmetric_keys/public_key.c), to cause a kernel panic and crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0d62e9dd6da45bbf0f33a8617afc5fe774c8f45f http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org • CWE-228: Improper Handling of Syntactically Invalid Structure CWE-310: Cryptographic Issues •
