Ubuntu Security Notice USN-5560-1

Ubuntu Security Notice USN-5560-1
Posted Aug 10, 2022
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5560-1 - Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service or execute arbitrary code. It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code.

linux, linux-aws, linux-azure-4.15, linux-dell300x, linux-gcp-4.15,
linux-kvm, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure-4.15: Linux kernel for Microsoft Azure Cloud systems
- linux-dell300x: Linux kernel for Dell 300x platforms
- linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi2: Linux kernel for Raspberry Pi systems
- linux-snapdragon: Linux kernel for Qualcomm Snapdragon processors

Details:

Zhenpeng Lin discovered that the network packet scheduler implementation in
the Linux kernel did not properly remove all references to a route filter
before freeing it in some situations. A local attacker could use this to
cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-2588)

It was discovered that the netfilter subsystem of the Linux kernel did not
prevent one nft object from referencing an nft set in another nft table,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or execute arbitrary code.
(CVE-2022-2586)

It was discovered that the block layer subsystem in the Linux kernel did
not properly initialize memory in some situations. A privileged local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2022-0494)

Hu Jiahui discovered that multiple race conditions existed in the Advanced
Linux Sound Architecture (ALSA) framework, leading to use-after-free
vulnerabilities. A local attacker could use these to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)

It was discovered that the implementation of the 6pack and mkiss protocols
in the Linux kernel did not handle detach events properly in some
situations, leading to a use-after-free vulnerability. A local attacker
could possibly use this to cause a denial of service (system crash).
(CVE-2022-1195)

Minh Yuan discovered that the floppy disk driver in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A
local attacker could possibly use this to cause a denial of service (system
crash) or execute arbitrary code. (CVE-2022-1652)

It was discovered that the Atheros ath9k wireless device driver in the
Linux kernel did not properly handle some error conditions, 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-2022-1679)

Norbert Slusarek discovered that a race condition existed in the perf
subsystem in the Linux kernel, resulting in a use-after-free vulnerability.
A privileged local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-1729)

It was discovered that the Marvell NFC device driver implementation in the
Linux kernel did not properly perform memory cleanup operations in some
situations, leading to a use-after-free vulnerability. A local attacker
could possibly use this to cause a denial of service (system crash) or
execute arbitrary code. (CVE-2022-1734)

Duoming Zhou discovered a race condition in the NFC subsystem in the Linux
kernel, leading to a use-after-free vulnerability. A privileged local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2022-1974)

Duoming Zhou discovered that the NFC subsystem in the Linux kernel did not
properly prevent context switches from occurring during certain atomic
context operations. A privileged local attacker could use this to cause a
denial of service (system crash). (CVE-2022-1975)

Minh Yuan discovered that the floppy driver in the Linux kernel contained a
race condition in some situations, 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-2022-33981)

Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel
did not properly perform data validation. A local attacker could use this
to escalate privileges in certain situations. (CVE-2022-34918)

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.
