19 Jun 2017 — An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be "jumped" over (the stack guard page is bypassed), this affects Linux Kernel versions 4.11.5 and earlier (the stackguard page was introduced in 2010). Se ha descubierto un problema en el tamaño de la página de stack guard en Linux; específicamente, una página 4k stack guard no es lo suficientemente grande y puede "saltarse" (se omite la página de stack guard).

17 Jun 2017 — sound/core/timer.c in the Linux kernel before 4.11.5 is vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time. El archivo sound/core/timer.c en el kernel de Linux anterior a versión 4.11.5, es vulnerable a una carrera de datos en el controlador de /dev/snd/timer de ALSA, resultando en que los usuarios locales sean capace... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ba3021b2c79b2fa9114f92790a99deb27a65b728 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

14 Jun 2017 — An information disclosure vulnerability in the kernel ION subsystem could enable a local malicious application to access data outside of its permission levels. This issue is rated as Low because it first requires compromising a privileged process. Product: Android. Versions: Kernel-3.18. Android ID: A-35644815. • http://www.securityfocus.com/bid/98875 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

13 Jun 2017 — The vmw_gb_surface_define_ioctl function (accessible via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.11.4 defines a backup_handle variable but does not give it an initial value. If one attempts to create a GB surface, with a previously allocated DMA buffer to be used as a backup buffer, the backup_handle variable does not get written to and is then later returned to user space, allowing local users to obtain sensitive information from uninitializ... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=07678eca2cf9c9a18584e546c2b2a0d0c9a3150c • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

07 Jun 2017 — It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.

27 May 2017 — The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel through 4.11.3 is too late in checking whether an overwrite of an skb data structure may occur, which allows local users to cause a denial of service (system crash) via crafted system calls. La función __ip6_append_data en el archivo net/ipv6/ip6_output.c en el kernel de Linux hasta versión 4.11.3, es demasiado tardía para comprobar si se puede sobrescribir una estructura de datos skb, lo que permite a los usuarios locales causar un... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=232cd35d0804cc241eb887bb8d4d9b3b9881c64a • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •

23 May 2017 — The crypto_skcipher_init_tfm function in crypto/skcipher.c in the Linux kernel through 4.11.2 relies on a setkey function that lacks a key-size check, which allows local users to cause a denial of service (NULL pointer dereference) via a crafted application.
