\nJuly 13, 2022<\/p>\n
linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15,
\nlinux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-raspi2,
\nlinux-snapdragon vulnerabilities
\n=========================================================================
\nA security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 18.04 LTS
\n– Ubuntu 16.04 ESM
\n– Ubuntu 14.04 ESM<\/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-4.15: Linux kernel for Microsoft Azure Cloud systems
\n– linux-gcp-4.15: 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-raspi2: Linux kernel for Raspberry Pi systems
\n– linux-snapdragon: Linux kernel for Qualcomm Snapdragon processors
\n– linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems
\n– linux-hwe: Linux hardware enablement (HWE) kernel
\n– linux-azure: Linux kernel for Microsoft Azure Cloud systems<\/p>\n
Details:<\/p>\n
Eric Biederman discovered that the cgroup process migration implementation
\nin the Linux kernel did not perform permission checks correctly in some
\nsituations. A local attacker could possibly use this to gain administrative
\nprivileges. (CVE-2021-4197)<\/p>\n
Jann Horn discovered that the FUSE file system in the Linux kernel
\ncontained a use-after-free vulnerability. A local attacker could use this
\nto cause a denial of service (system crash) or possibly execute arbitrary
\ncode. (CVE-2022-1011)<\/p>\n
Duoming Zhou discovered that the 6pack protocol implementation in the Linux
\nkernel did not handle detach events properly in some situations, leading to
\na use-after-free vulnerability. A local attacker could use this to cause a
\ndenial of service (system crash). (CVE-2022-1198)<\/p>\n
Duoming Zhou discovered that the AX.25 amateur radio protocol
\nimplementation in the Linux kernel did not handle detach events properly in
\nsome situations. A local attacker could possibly use this to cause a denial
\nof service (system crash) or execute arbitrary code. (CVE-2022-1199)<\/p>\n
Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol
\nimplementation in the Linux kernel during device detach operations. A local
\nattacker could possibly use this to cause a denial of service (system
\ncrash). (CVE-2022-1204)<\/p>\n
Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol
\nimplementation in the Linux kernel, leading to use-after-free
\nvulnerabilities. A local attacker could possibly use this to cause a denial
\nof service (system crash). (CVE-2022-1205)<\/p>\n
It was discovered that the PF_KEYv2 implementation in the Linux kernel did
\nnot properly initialize kernel memory in some situations. A local attacker
\ncould use this to expose sensitive information (kernel memory).
\n(CVE-2022-1353)<\/p>\n
It was discovered that the implementation of X.25 network protocols in the
\nLinux kernel did not terminate link layer sessions properly. A local
\nattacker could possibly use this to cause a denial of service (system
\ncrash). (CVE-2022-1516)<\/p>\n
Zheyu Ma discovered that the Silicon Motion SM712 framebuffer driver in the
\nLinux kernel did not properly handle very small reads. A local attacker
\ncould use this to cause a denial of service (system crash). (CVE-2022-2380)<\/p>\n
It was discovered that the Microchip CAN BUS Analyzer interface
\nimplementation in the Linux kernel did not properly handle certain error
\nconditions, leading to a double-free. A local attacker could possibly use
\nthis to cause a denial of service (system crash). (CVE-2022-28389)<\/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
