https://notcve.org/view.php?id=CVE-2018-13405
06 Jul 2018 — The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non... • https://www.exploit-db.com/exploits/45033 • CWE-269: Improper Privilege Management CWE-284: Improper Access Control •

12 Jun 2018 — In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the 'ie_len' argument can cause a buffer overflow in all Android releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel. En la función wmi_set_ie(), el código de validación de longitud no gestiona correctamente los desbordamientos de enteros sin firmar.

22 May 2018 — A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/
