A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability.

Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the f2fs file system in the Linux kernel did not
properly validate metadata in some situations. An attacker could use this
to construct a malicious f2fs image that, when mounted and operated on,
could cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-19449)
It was discovered that the Infiniband RDMA userspace connection manager
implementation in the Linux kernel contained a race condition leading to a

Title: Linux kernel vulnerability
Summary: The system could be made to crash under certain conditions.
It was discovered that the Linux kernel did not properly account for the
memory usage of certain IPC objects. A local attacker could use this to
cause a denial of service (memory exhaustion).
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
