USN-5358-1: Linux kernel vulnerabilities


=========================================================================
Ubuntu Security Notice USN-5358-1
March 31, 2022

linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.13, linux-hwe-5.4,
linux-kvm, linux-oracle, linux-oracle-5.4 vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

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-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-hwe-5.13: Linux hardware enablement (HWE) kernel
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
- linux-oracle-5.4: Linux kernel for Oracle Cloud systems

Details:

It was discovered that the network traffic control implementation in the
Linux kernel contained a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-1055)

It was discovered that the IPsec implementation in the Linux
kernel did not properly allocate enough memory when performing ESP
transformations, leading to a heap-based buffer overflow. A local
attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-27666)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

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.
