\nMarch 09, 2022<\/p>\n
linux, linux-aws, linux-aws-5.13, linux-azure, linux-azure-5.13,
\nlinux-gcp, linux-gcp-5.13, linux-hwe-5.13, linux-kvm, linux-oem-5.14,
\nlinux-oracle, linux-oracle-5.13, linux-raspi vulnerabilities
\n==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 21.10
\n– Ubuntu 20.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
\n– linux: Linux kernel
\n– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
\n– linux-azure: Linux kernel for Microsoft Azure Cloud systems
\n– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
\n– linux-kvm: Linux kernel for cloud environments
\n– linux-oracle: Linux kernel for Oracle Cloud systems
\n– linux-raspi: Linux kernel for Raspberry Pi systems
\n– linux-aws-5.13: Linux kernel for Amazon Web Services (AWS) systems
\n– linux-azure-5.13: Linux kernel for Microsoft Azure cloud systems
\n– linux-gcp-5.13: Linux kernel for Google Cloud Platform (GCP) systems
\n– linux-hwe-5.13: Linux hardware enablement (HWE) kernel
\n– linux-oem-5.14: Linux kernel for OEM systems
\n– linux-oracle-5.13: Linux kernel for Oracle Cloud systems<\/p>\n
Details:<\/p>\n
Nick Gregory discovered that the Linux kernel incorrectly handled network
\noffload functionality. A local attacker could use this to cause a denial of
\nservice or possibly execute arbitrary code. (CVE-2022-25636)<\/p>\n
Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano
\nGiuffrida discovered that hardware mitigations added by ARM to their
\nprocessors to address Spectre-BTI were insufficient. A local attacker could
\npotentially use this to expose sensitive information. (CVE-2022-23960)<\/p>\n
Max Kellermann discovered that the Linux kernel incorrectly handled Unix
\npipes. A local attacker could potentially use this to modify any file that
\ncould be opened for reading. (CVE-2022-0847)<\/p>\n
Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano
\nGiuffrida discovered that hardware mitigations added by Intel to their
\nprocessors to address Spectre-BTI were insufficient. A local attacker could
\npotentially use this to expose sensitive information. (CVE-2022-0001,
\nCVE-2022-0002)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
\npackage versions:<\/p>\n

After a standard system update you need to reboot your computer to make
\nall the necessary changes.<\/p>\n
ATTENTION: 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.<\/p>\n
