The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c at the Linux kernel version 3.4 and up to and including 4.15 has an integer-overflow vulnerability allowing local users with access to the udldrmfb driver to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space. La función udl_fb_mmap en drivers/gpu/drm/udl/udl_fb.c en el kernel de Linux en su versión 3.4 y hasta e incluyendo la versión 4.15 tiene una vulnerabilidad de desbordamiento de enteros que permite que usuarios locales con acceso al controlador udldrmfb obtengan permisos totales de lectura y escritura en páginas físicas del kernel, lo que resulta en la ejecución de código en el espacio del kernel. A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function.

CVSS: 7.1EPSS: 0%CPEs: 6EXPL: 1CVE-2018-1094 – kernel: NULL pointer dereference in ext4/xattr.c:ext4_xattr_inode_hash() causes crash with crafted ext4 image
https://notcve.org/view.php?id=CVE-2018-1094
The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.15.15 does not always initialize the crc32c checksum driver, which allows attackers to cause a denial of service (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted ext4 image. La función ext4_fill_super en fs/ext4/super.c en el kernel de Linux hasta la versión 4.15.15 no inicializa siempre el controlador de las sumas de verificación crc32c, lo que permite que los atacantes provoquen una denegación de servicio (desreferencia de puntero NULL en ext4_xattr_inode_hash y cierre inesperado del sistema) mediante una imagen ext4 manipulada. The Linux kernel is vulnerable to a NULL pointer dereference in the ext4/xattr.c:ext4_xattr_inode_hash() function. An attacker could trick a legitimate user or a privileged attacker could exploit this to cause a NULL pointer dereference with a crafted ext4 image. • http://openwall.com/lists/oss-security/2018/03/29/1 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://bugzilla.kernel.org/show_bug.cgi?id=199183 https://bugzilla.redhat.com/show_bug.cgi?id=1560788 https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit/?id=18db4b4e6fc31eda838dd1c1296d67dbcb3dc957 https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.g • CWE-476: NULL Pointer Dereference •
