CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2018-9568 – kernel: Memory corruption due to incorrect socket cloning
https://notcve.org/view.php?id=CVE-2018-9568
In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android.

CVSS: 4.7EPSS: 0%CPEs: 5EXPL: 0CVE-2018-19854 – kernel: Information Disclosure in crypto_report_one in crypto/crypto_user.c
https://notcve.org/view.php?id=CVE-2018-19854
An issue was discovered in the Linux kernel before 4.19.3. crypto_report_one() and related functions in crypto/crypto_user.c (the crypto user configuration API) do not fully initialize structures that are copied to userspace, potentially leaking sensitive memory to user programs. NOTE: this is a CVE-2013-2547 regression but with easier exploitability because the attacker does not need a capability (however, the system must have the CONFIG_CRYPTO_USER kconfig option). Se ha descubierto un problema en el kernel de Linux hasta antes de la versión 4.19.3. crypto_report_one() y otras funciones relacionadas en crypto/crypto_user.c (la API de configuración de usuarios crypto) no inicializan completamente las estructuras que se copian en el espacio de usuario, lo que podría filtrar memoria sensible a los programas del usuario. NOTA: esta es una regresión de CVE-2013-2547, pero con una explotabilidad más sencilla. Esto se deba a que el atacante no necesita una capacidad (sin embargo, el sistema debe tener la opción de kconfig CONFIG_CRYPTO_USER). • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f43f39958beb206b53292801e216d9b8a660f087 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://github.com/torvalds/linux/commit/f43f39958beb206b53292801e216d9b8a660f087 https://kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.3 https://usn.ubuntu.com/3872-1 https://usn.ubuntu.com/3878-1 https://usn.ubuntu.com/3878-2 https://usn.ubuntu.com/3901-1 https:/&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2018-19824
In the Linux kernel through 4.19.6, a local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c. En el kernel de Linux hasta la versión 4.19.6, un usuario local podría explotar memoria previamente liberada en el controlador ALSA suministrando un dispositivo de sonido USB malicioso (con cero interfaces) que no se maneja correctamente en usb_audio_probe en sound/usb/card.c. A flaw was found In the Linux kernel, through version 4.19.6, where a local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c. An attacker could corrupt memory and possibly escalate privileges if the attacker is able to have physical access to the system. • http://www.securityfocus.com/bid/106109 https://access.redhat.com/errata/RHSA-2019:2703 https://bugzilla.suse.com/show_bug.cgi?id=1118152 https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=5f8cf712582617d523120df67d392059eaf2fc4b https://github.com/torvalds/linux/commit/5f8cf712582617d523120df67d392059eaf2fc4b https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://lists.debian.org/debian- • CWE-416: Use After Free •

A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one. Se ha detectado un fallo de seguridad en el kernel de Linux de manera que el subsistema "cleancache" borre un inode después del truncado de archivos final (eliminación). El nuevo archivo creado con el mismo inode podría contener páginas restantes del "cleancache" y los datos antiguos del mismo, en vez de los del nuevo archivo. • http://www.securityfocus.com/bid/106009 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16862 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://lore.kernel.org/patchwork/patch/1011367 https://seclists.org/oss-sec/2018/q4/169 https://usn.ubuntu.com/3879-1 https://usn.ubuntu.com/3879-2 https://usn. • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.5EPSS: 0%CPEs: 15EXPL: 0CVE-2018-14646 – kernel: NULL pointer dereference in af_netlink.c:__netlink_ns_capable() allows for denial of service
https://notcve.org/view.php?id=CVE-2018-14646
The Linux kernel before 4.15-rc8 was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service. El kernel de Linux en versiones anteriores a la 4.15-rc8 era vulnerable a un error de desreferencia de puntero NULL en la función __netlink_ns_capable() en el archivo net/netlink/af_netlink.c. Un atacante local podría explotarlo cuando un espacio de nombres de red con un netnsid se asigne para provocar un kernel de pánico y ataque de denegación de servicio (DoS). The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. • https://access.redhat.com/errata/RHSA-2018:3651 https://access.redhat.com/errata/RHSA-2018:3666 https://access.redhat.com/errata/RHSA-2018:3843 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14646 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f428fe4a04cc339166c8bbd489789760de3a0cee https://marc.info/?l=linux-netdev&m=151500466401174&w=2 https://access.redhat.com/security/cve/CVE-2018-14646 https://bugzilla.redhat.com/show_bug.cgi?id=1630124 • CWE-476: NULL Pointer Dereference •
