\nUbuntu Security Notice USN-5358-1
\nMarch 31, 2022<\/p>\n
linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.13, linux-hwe-5.4,
\nlinux-kvm, linux-oracle, linux-oracle-5.4 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
\n– Ubuntu 18.04 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-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-azure: Linux kernel for Microsoft Azure Cloud systems
\n– linux-hwe-5.13: Linux hardware enablement (HWE) kernel
\n– linux-hwe-5.4: Linux hardware enablement (HWE) kernel
\n– linux-oracle-5.4: Linux kernel for Oracle Cloud systems<\/p>\n
Details:<\/p>\n
It was discovered that the network traffic control implementation in the
\nLinux kernel contained a use-after-free vulnerability. A local attacker
\ncould use this to cause a denial of service (system crash) or possibly
\nexecute arbitrary code. (CVE-2022-1055)<\/p>\n
It was discovered that the IPsec implementation in the Linux
\nkernel did not properly allocate enough memory when performing ESP
\ntransformations, leading to a heap-based buffer overflow. A local
\nattacker could use this to cause a denial of service (system crash)
\nor possibly execute arbitrary code. (CVE-2022-27666)<\/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
