Details

Adam Zabrocki discovered that the Intel i915 kernel mode graphics driver in
the Linux kernel did not properly restrict mmap() ranges in some
situations. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2019-11085)

It was discovered that a race condition leading to a use-after-free existed
in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux
kernel. The RDS protocol is disabled via blocklist by default in Ubuntu.
If enabled, a local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2019-11815)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly zero out memory in some situations. A local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2019-11833)

It was discovered that the Bluetooth Human Interface Device Protocol (HIDP)
implementation in the Linux kernel did not properly verify strings were
NULL terminated in certain situations. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2019-11884)
