25 Jan 2019 — A denial of service vulnerability was found in rsyslog in the imptcp module. An attacker could send a specially crafted message to the imptcp socket, which would cause rsyslog to crash. Versions before 8.27.0 are vulnerable. Se ha detectado una vulnerabilidad de denegación de servicio (DoS) en rsyslog en el módulo imptcp. Un atacante podría enviar un mensaje especialmente manipulado al socket imptcp, lo que conduciría al cierre forzado de rsyslog. • https://access.redhat.com/errata/RHBA-2019:2501 • CWE-190: Integer Overflow or Wraparound •

12 Dec 2018 — The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.

https://notcve.org/view.php?id=CVE-2018-18559
22 Oct 2018 — In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists.
