A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS
\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-gcp: Linux kernel for Google Cloud Platform (GCP) systems
\n– linux-gkeop: Linux kernel for Google Container Engine (GKE) systems
\n– linux-ibm: Linux kernel for IBM cloud systems
\n– linux-intel-iotg: Linux kernel for Intel IoT platforms
\n– linux-kvm: Linux kernel for cloud environments
\n– linux-lowlatency: Linux low latency kernel
\n– linux-oracle: Linux kernel for Oracle Cloud systems
\n– linux-raspi: Linux kernel for Raspberry Pi systems
\n– linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
\n– linux-hwe-5.15: Linux hardware enablement (HWE) kernel
\n– linux-lowlatency-hwe-5.15: Linux low latency kernel
\n– linux-oracle-5.15: Linux kernel for Oracle Cloud systems<\/p>\n
Details:<\/p>\n
It was discovered that the NFSD implementation in the Linux kernel did not
\nproperly handle some RPC messages, leading to a buffer overflow. A remote
\nattacker could use this to cause a denial of service (system crash) or
\npossibly execute arbitrary code. (CVE-2022-43945)<\/p>\n
Jann Horn discovered that the Linux kernel did not properly track memory
\nallocations for anonymous VMA mappings in some situations, leading to
\npotential data structure reuse. A local attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.
\n(CVE-2022-42703)<\/p>\n
It was discovered that a memory leak existed in the IPv6 implementation of
\nthe Linux kernel. A local attacker could use this to cause a denial of
\nservice (memory exhaustion). (CVE-2022-3524)<\/p>\n
It was discovered that a race condition existed in the Bluetooth subsystem
\nin the Linux kernel, leading to a use-after-free vulnerability. A local
\nattacker could use this to cause a denial of service (system crash) or
\npossibly execute arbitrary code. (CVE-2022-3564)<\/p>\n
It was discovered that the ISDN implementation of the Linux kernel
\ncontained a use-after-free vulnerability. A privileged user could use this
\nto cause a denial of service (system crash) or possibly execute arbitrary
\ncode. (CVE-2022-3565)<\/p>\n
It was discovered that the TCP implementation in the Linux kernel contained
\na data race condition. An attacker could possibly use this to cause
\nundesired behaviors. (CVE-2022-3566)<\/p>\n
It was discovered that the IPv6 implementation in the Linux kernel
\ncontained a data race condition. An attacker could possibly use this to
\ncause undesired behaviors. (CVE-2022-3567)<\/p>\n
It was discovered that the Realtek RTL8152 USB Ethernet adapter driver in
\nthe Linux kernel did not properly handle certain error conditions. A local
\nattacker with physical access could plug in a specially crafted USB device
\nto cause a denial of service (memory exhaustion). (CVE-2022-3594)<\/p>\n
It was discovered that a null pointer dereference existed in the NILFS2
\nfile system implementation in the Linux kernel. A local attacker could use
\nthis to cause a denial of service (system crash). (CVE-2022-3621)<\/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
