CVE-2018-17972 – kernel: Unprivileged users able to inspect kernel stacks of arbitrary tasks
https://notcve.org/view.php?id=CVE-2018-17972
03 Oct 2018 — An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. Se descubrió un problema en la función proc_pid_stack en fs/proc/base.c en el kernel de Linux hasta la versión 4.18.11. No asegura que solo root pueda inspeccionar la pila del kernel de una tarea arbitraria, lo que permite... • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00043.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2018-9363 – kernel: Buffer overflow in hidp_process_report
https://notcve.org/view.php?id=CVE-2018-9363
02 Oct 2018 — In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds write with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-65853588 References: Upstream kernel.

CVE-2018-14634 – Linux Kernel 2.6.x / 3.10.x / 4.14.x (RedHat / Debian / CentOS) (x64) - 'Mutagen Astronomy' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-14634
25 Sep 2018 — An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable. Se ha encontrado un error de desbordamiento de enteros en la función create_elf_tables() del kernel de Linux.

CVE-2018-14633 – kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target
https://notcve.org/view.php?id=CVE-2018-14633
25 Sep 2018 — A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system... • http://www.securityfocus.com/bid/105388 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2018-17182 – Linux Kernel - VMA Use-After-Free via Buggy vmacache_flush_all() Fastpath Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-17182
19 Sep 2018 — An issue was discovered in the Linux kernel through 4.18.8. The vmacache_flush_all function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.18.8. La función vmacache_flush_all en mm/vmacache.c manipula incorrectamente los desbordamientos de números de secuencias. • https://www.exploit-db.com/exploits/45497 • CWE-416: Use After Free •
CVE-2018-10853 – kernel: kvm: guest userspace to guest kernel write
https://notcve.org/view.php?id=CVE-2018-10853
11 Sep 2018 — A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest.

CVE-2018-16658 – kernel: Information leak in cdrom_ioctl_drive_status
https://notcve.org/view.php?id=CVE-2018-16658
07 Sep 2018 — An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940. Se ha descubierto un problema en el kernel de Linux hasta antes de la versión 4.18.6.
