Vulnerability from variot
There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/n_tty.c. Linux Kernel Is vulnerable to the use of freed memory.Information is obtained and service operation is interrupted (DoS) It may be put into a state. Description:
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Description:
Red Hat Advanced Cluster Management for Kubernetes 2.2.4 images

========================================================================== Ubuntu Security Notice USN-4344-1 April 28, 2020
linux-gke-5.0, linux-oem-osp11 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16234)
It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19051)
Tristan Madani discovered that the block I/O tracing implementation in the Linux kernel contained a race condition. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-19768)
It was discovered that the vhost net driver in the Linux kernel contained a stack buffer overflow. A local attacker with the ability to perform ioctl() calls on /dev/vhost-net could use this to cause a denial of service (system crash). A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2020-8648)
Shijie Luo discovered that the ext4 file system implementation in the Linux kernel did not properly check for a too-large journal size. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (soft lockup). (CVE-2020-8992)
Jordy Zomer discovered that the floppy driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-9383)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: linux-image-5.0.0-1035-gke 5.0.0-1035.36 linux-image-5.0.0-1050-oem-osp1 5.0.0-1050.55 linux-image-gke-5.0 5.0.0.1035.23 linux-image-oem-osp1 5.0.0.1050.53
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. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. 8) - aarch64, noarch, ppc64le, s390x, x86_64

A local attacker could\npossibly use this to cause a denial of service (system crash). \n(CVE-2019-16234)\n\nIt was discovered that the Intel WiMAX 2400 driver in the Linux kernel did\nnot properly deallocate memory in certain situations. A local attacker\ncould use this to cause a denial of service (kernel memory exhaustion). \n(CVE-2019-19051)\n\nTristan Madani discovered that the block I/O tracing implementation in the\nLinux kernel contained a race condition. A local attacker could use this to\ncause a denial of service (system crash) or possibly expose sensitive\ninformation. (CVE-2019-19768)\n\nIt was discovered that the vhost net driver in the Linux kernel contained a\nstack buffer overflow. A local attacker with the ability to perform ioctl()\ncalls on /dev/vhost-net could use this to cause a denial of service (system\ncrash). A local attacker could possibly use this\nto cause a denial of service (system crash) or expose sensitive\ninformation. (CVE-2020-8648)\n\nShijie Luo discovered that the ext4 file system implementation in the Linux\nkernel did not properly check for a too-large journal size. An attacker\ncould use this to construct a malicious ext4 image that, when mounted,\ncould cause a denial of service (soft lockup). (CVE-2020-8992)\n\nJordy Zomer discovered that the floppy driver in the Linux kernel did not\nproperly check for errors in some situations. A local attacker could\npossibly use this to cause a denial of service (system crash) or possibly\nexpose sensitive information. (CVE-2020-9383)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 18.04 LTS:\n linux-image-5.0.0-1035-gke 5.0.0-1035.36\n linux-image-5.0.0-1050-oem-osp1 5.0.0-1050.55\n linux-image-gke-5.0 5.0.0.1035.23\n linux-image-oem-osp1 5.0.0.1050.53\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. 8) - aarch64, noarch, ppc64le, s390x, x86_64\n\n3.
