21 Nov 2018 — The vcpu_scan_ioapic function in arch/x86/kvm/x86.c in the Linux kernel through 4.19.2 allows local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized.

CVSS: 7.0EPSS: 0%CPEs: 4EXPL: 9CVE-2018-18955 – Linux - Nested User Namespace idmap Limit Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-18955
16 Nov 2018 — In the Linux kernel 4.15.x through 4.19.x before 4.19.2, map_write() in kernel/user_namespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace, as demonstrated by reading /etc/shadow. This occurs because an ID transformation takes place properly for the namespaced-to-kernel direction but not for the kernel-to-namespaced directi... • https://packetstorm.news/files/id/150489 • CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 0%CPEs: 10EXPL: 2CVE-2018-18281 – kernel: TLB flush happens too late on mremap
https://notcve.org/view.php?id=CVE-2018-18281
29 Oct 2018 — Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. This is fixed in the following kernel versions: 4.9.135, 4.14.78, 4.18.16, 4.19. Desde la versión 3.2 del kernel de Linux, la syscall mremap(... • https://packetstorm.news/files/id/150001 • CWE-459: Incomplete Cleanup CWE-672: Operation on a Resource after Expiration or Release •

27 Oct 2018 — An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc 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 and CVE-2018-16658. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.19.

08 Oct 2018 — A missing address check in the callers of the show_opcodes() in the Linux kernel allows an attacker to dump the kernel memory at an arbitrary kernel address into the dmesg log. La falta de una comprobación de direcciones en los llamantes de show_opcodes() en el kernel de Linux permite que un atacante vuelque la memoria del kernel en una dirección arbitraria del kernel en el registro dmesg. • http://www.securitytracker.com/id/1041804 • CWE-20: Improper Input Validation •

18 Sep 2018 — A security flaw was found in the ip_frag_reasm() function in net/ipv4/ip_fragment.c in the Linux kernel from 4.19-rc1 to 4.19-rc3 inclusive, which can cause a later system crash in ip_do_fragment(). With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote denial-of-service.
