https://notcve.org/view.php?id=CVE-2017-18202
The __oom_reap_task_mm function in mm/oom_kill.c in the Linux kernel before 4.14.4 mishandles gather operations, which allows attackers to cause a denial of service (TLB entry leak or use-after-free) or possibly have unspecified other impact by triggering a copy_to_user call within a certain time window. La función __oom_reap_task_mm en mm/oom_kill.c en el kernel de Linux, en versiones anteriores a la 4.14.4, gestiona de manera incorrecta las operaciones de recopilación. Esto permite que los atacantes provoquen una denegación de servicio (filtrado de entrada TLB o uso de memoria previamente liberada) u otro tipo de impacto sin especificar desencadenando una llamada copy_to_user en un periodo de tiempo determinado.

A NULL pointer dereference was found in the net/rds/rdma.c __rds_rdma_map() function in the Linux kernel before 4.14.7 allowing local attackers to cause a system panic and a denial-of-service, related to RDS_GET_MR and RDS_GET_MR_FOR_DEST. Se ha encontrado una desreferencia de puntero NULL en la función net/rds/rdma.c __rds_rdma_map() en el kernel de Linux, en versiones anteriores a la 4.14.7, que permite que atacantes locales provoquen un error en el sistema y una denegación de servicio (DoS). Esto se relaciona con RDS_GET_MR y RDS_GET_MR_FOR_DEST. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f3069c6d33f6ae63a1668737bc78aaaa51bff7ca http://www.securityfocus.com/bid/103185 https://bugzilla.redhat.com/show_bug.cgi?id=1527393 https://github.com/torvalds/linux/commit/f3069c6d33f6ae63a1668737bc78aaaa51bff7ca https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://patchwork.kernel.org/patch/10096441 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3674-1 https • CWE-476: NULL Pointer Dereference •

The f2fs implementation in the Linux kernel before 4.14 mishandles reference counts associated with f2fs_wait_discard_bios calls, which allows local users to cause a denial of service (BUG), as demonstrated by fstrim. La implementación f2fs en el kernel de Linux, en versiones anteriores a la 4.14, gestiona erróneamente las cuentas asociadas a las llamadas f2fs_wait_discard_bios.
