Summary:

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gkeop: Linux kernel for Google Container Engine (GKE) systems
- linux-ibm: Linux kernel for IBM cloud systems
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
- linux-ibm-5.4: Linux kernel for IBM cloud systems
- linux-oracle-5.4: Linux kernel for Oracle Cloud systems
- linux-raspi-5.4: Linux kernel for Raspberry Pi systems

Details:

Jann Horn discovered that the Linux kernel did not properly track memory
allocations for anonymous VMA mappings in some situations, leading to
potential data structure reuse. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-42703)

It was discovered that a memory leak existed in the IPv6 implementation of
the Linux kernel. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2022-3524)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to 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-2022-3564)

It was discovered that the ISDN implementation of the Linux kernel
contained a use-after-free vulnerability. A privileged user could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3565)

It was discovered that the TCP implementation in the Linux kernel contained
a data race condition. An attacker could possibly use this to cause
undesired behaviors. (CVE-2022-3566)

It was discovered that the IPv6 implementation in the Linux kernel
contained a data race condition. An attacker could possibly use this to
cause undesired behaviors. (CVE-2022-3567)

It was discovered that the Realtek RTL8152 USB Ethernet adapter driver in
the Linux kernel did not properly handle certain error conditions. A local
attacker with physical access could plug in a specially crafted USB device
to cause a denial of service (memory exhaustion). (CVE-2022-3594)

It was discovered that a null pointer dereference existed in the NILFS2
file system implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash). (CVE-2022-3621)

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.
