Red Hat Security Advisory 2019-2043-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, denial of service, information leakage, null pointer, and use-after-free vulnerabilities.

Issues addressed include buffer overflow, denial of service, information leakage, null pointer, and use-after-free vulnerabilities.
bac8beb8ce1ab8e43186837924865c4859c9dd53f0986287f9d903fc550005c1Ubuntu Security Notice 3678-4 - Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle corrupted meta data in some situations. An attacker could use this to specially craft an ext4 file system that caused a denial of service when mounted. It was discovered that the 802.11 software simulator implementation in the Linux kernel contained a memory leak when handling certain error conditions. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.

This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS. It was discovered that the netfilter subsystem of the Linux kernel did not properly validate ebtables offsets. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

An attacker could use this to specially craft an ext4 file system that caused a denial of service when mounted. It was discovered that the cdrom driver in the Linux kernel contained an incorrect bounds check. A local attacker could use this to expose sensitive information.

9eb8e7aa9a0d4aa6ddced7f3c8e17089dc358de41a491f619dde8e9fa99a51e9Alexei Starovoitov discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel contained a branch-pruning logic issue around unreachable code. A local attacker could use this to cause a denial of service. The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a root directory with a zero i_links_count, which allows attackers to cause a denial of service (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image. Various other issues were also addressed.
