https://notcve.org/view.php?id=CVE-2018-20836
An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. Fue descubierto un fallo en el kernel de Linux anterior a 4.20. Hay una condición de carrera en smp_task_timedout() y smp_task_done() en drivers/scsi/libsas/sas_expander.c, permitiendo el uso después de liberación de memoria. A flaw was found in the Linux kernel’s implementation of the SAS expander subsystem, where a race condition exists in the smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00025.html http://www.securityfocus.com/bid/108196 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b90cd6f2b905905fb42671009dc0e27c310a16ae https://github.com/torvalds/linux/commit/b90cd6f2b905905fb42671009dc0e27c310a16ae https://lists.debian.org/debian-lts-announce/2019/08/msg00016.html https://lists.debian.org/debian-lts-announce/2019/08/msg00017.h • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

An issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c.

https://notcve.org/view.php?id=CVE-2019-11599
The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. La implementación del coredump en el kernel de Linux en versiones anteriores a 5.0.10, no utiliza mecanismos de bloqueo u otros mecanismos para evitar cambios en el layout de vma o en los flags vma mientras se ejecuta, lo que permite a los usuarios locales obtener información sensible, causar una denegación de servicio o posiblemente tener otro impacto no especificado al activar una condición de carrera con llamadas mmget_not_zero o get_task_mm. Esto está relacionado con fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, y drivers/infiniband/core/uverbs_main.c A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs.
