https://notcve.org/view.php?id=CVE-2017-9075
The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel through 4.11.1 mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890. La función sctp_v6_create_accept_sk en net/sctp/ipv6.c en el kernel de Linux hasta la versión 4.11.1 gestiona de manera incorrecta la herencia, lo que permite que usuarios locales provoquen una denegación de servicio (DoS) o, probablemente, causen otro impacto no especificado mediante llamadas de sistema manipuladas. Este problema está relacionado con CVE-2017-8890.

https://notcve.org/view.php?id=CVE-2017-7495
fs/ext4/inode.c in the Linux kernel before 4.6.2, when ext4 data=ordered mode is used, mishandles a needs-flushing-before-commit list, which allows local users to obtain sensitive information from other users' files in opportunistic circumstances by waiting for a hardware reset, creating a new file, making write system calls, and reading this file. En el archivo fs/ext4/inode.c en el kernel de Linux anterior a versión 4.6.2, cuando es usado el modo data=ordered de ext4, maneja inapropiadamente una lista de necesidades de descarga antes de confirmar, lo que permite a los usuarios locales obtener información confidencial de los archivos de otros usuarios en circunstancias oportunistas al esperar un reinicio del hardware, crear un archivo nuevo, hacer llamadas al sistema de escritura y leer este archivo. A vulnerability was found in the Linux kernel where filesystems mounted with data=ordered mode may allow an attacker to read stale data from recently allocated blocks in new files after a system 'reset' by abusing ext4 mechanics of delayed allocation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=06bd3c36a733ac27962fea7d6f47168841376824 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.2 http://www.openwall.com/lists/oss-security/2017/05/15/2 http://www.securityfocus.com/bid/98491 https://bugzilla.redhat.com/show_bug.cgi?id=1450261 https://github.com/torvalds/linux/commit/06bd3c36a733ac27962fea7d6f47168841376824 https://source.android.com/security/bulletin/2017-09-01 https://access.redhat.com/security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-665: Improper Initialization •
