CVE-2018-14617 – Ubuntu Security Notice USN-4094-1
https://notcve.org/view.php?id=CVE-2018-14617
27 Jul 2018 — An issue was discovered in the Linux kernel through 4.17.10. There is a NULL pointer dereference and panic in hfsplus_lookup() in fs/hfsplus/dir.c when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.17.10. Hay una desreferencia de puntero NULL y pánico en hfsplus_lookup() en fs/hfsplus/dir.c cuando se abre un archivo (que supue... • http://www.securityfocus.com/bid/104917 • CWE-476: NULL Pointer Dereference •
CVE-2017-18344 – Linux Kernel 4.14.7 (Ubuntu 16.04 / CentOS 7) - (KASLR & SMEP Bypass) Arbitrary File Read
https://notcve.org/view.php?id=CVE-2017-18344
26 Jul 2018 — The timer_create syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent->sigev_notify field, which leads to out-of-bounds access in the show_timer function (called when /proc/$PID/timers is read). This allows userspace applications to read arbitrary kernel memory (on a kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE).

26 Jul 2018 — A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image.

CVE-2018-10901 – kernel: kvm: vmx: host GDT limit corruption
https://notcve.org/view.php?id=CVE-2018-10901
26 Jul 2018 — A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.

CVE-2018-13405 – Linux (Ubuntu) - Other Users coredumps Can Be Read via setgid Directory and killpriv Bypass
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.
