Ubuntu 18.04 LTS: USN-6740-1 Critical: Kernel Denial Of Service Risks

ubuntu
Calendar Grey April 19, 2024
Dist Ubuntu Esm H88
Multiple security enhancements for the Ubuntu Linux kernel tackle denial of service vulnerabilities among others; urgent patches are now out. Ensure your system's safety!
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux: Linux kernel

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems

- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems

- linux-kvm: Linux kernel for cloud environments

- linux-oracle: Linux kernel for Oracle Cloud systems

- linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems

- linux-azure: Linux kernel for Microsoft Azure Cloud systems

- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems

- linux-hwe: Linux hardware enablement (HWE) kernel

Details:

Wei Chen discovered that a race condition existed in the TIPC protocol

implementation in the Linux kernel, leading to a null pointer dereference

vulnerability. A local attacker could use this to cause a denial of service

(system crash). (CVE-2023-1382)

It was discovered that the virtio network implement...

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.
