Ubuntu Security Notice USN-5505-1
July 07, 2022

linux-lts-xenial, linux-kvm vulnerabilities
==========================================================================

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

- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-kvm: Linux kernel for cloud environments
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

Norbert Slusarek discovered a race condition in the CAN BCM networking
protocol of the Linux kernel leading to multiple use-after-free
vulnerabilities. A local attacker could use this issue to execute arbitrary
code. (CVE-2021-3609)

Likang Luo discovered that a race condition existed in the Bluetooth
subsystem of 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-2021-3752)

It was discovered that the NFC subsystem in the Linux kernel contained a
use-after-free vulnerability in its NFC Controller Interface (NCI)
implementation. A local attacker could possibly use this to cause a denial
of service (system crash) or execute arbitrary code. (CVE-2021-3760)

Szymon Heidrich discovered that the USB Gadget subsystem in the Linux
kernel did not properly restrict the size of control requests for certain
gadget types, leading to possible out of bounds reads or writes. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2021-39685)

It was discovered that the Ion Memory Manager subsystem in the Linux kernel
contained 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-2021-39714)

Eric Biederman discovered that the cgroup process migration implementation
in the Linux kernel did not perform permission checks correctly in some
situations. A local attacker could possibly use this to gain administrative
privileges. (CVE-2021-4197)

Lin Ma discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel contained a race condition, 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-2021-4202)

Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in
the Linux kernel did not perform a GPU TLB flush in some situations. A
local attacker could use this to cause a denial of service or possibly
execute arbitrary code. (CVE-2022-0330)

It was discovered that the PF_KEYv2 implementation in the Linux kernel did
not properly initialize kernel memory in some situations. A local attacker
could use this to expose sensitive information (kernel memory).
(CVE-2022-1353)

It was discovered that the virtual graphics memory manager implementation
in the Linux kernel was subject to a race condition, potentially leading to
an information leak. (CVE-2022-1419)

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)

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) or execute
arbitrary code. (CVE-2022-1734)

It was discovered that some Intel processors did not completely perform
cleanup actions on multi-core shared buffers. A local attacker could
possibly use this to expose sensitive information. (CVE-2022-21123)

It was discovered that some Intel processors did not completely perform
cleanup actions on microarchitectural fill buffers. A local attacker could
possibly use this to expose sensitive information. (CVE-2022-21125)

It was discovered that some Intel processors did not properly perform
cleanup during specific special register write operations. A local attacker
could possibly use this to expose sensitive information. (CVE-2022-21166)

It was discovered that the USB Gadget file system interface in the Linux
kernel contained 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-2022-24958)

赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not
properly perform reference counting in some error conditions. A local
attacker could use this to cause a denial of service. (CVE-2022-28356)

It was discovered that the 8 Devices USB2CAN interface implementation in
the Linux kernel did not properly handle certain error conditions, leading
to a double-free. A local attacker could possibly use this to cause a
denial of service (system crash). (CVE-2022-28388)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 ESM:
  linux-image-4.4.0-1110-kvm      4.4.0-1110.120
  linux-image-kvm                 4.4.0.1110.107

Ubuntu 14.04 ESM:
  linux-image-4.4.0-229-generic   4.4.0-229.263~14.04.1
  linux-image-4.4.0-229-lowlatency  4.4.0-229.263~14.04.1
  linux-image-generic-lts-xenial  4.4.0.229.199
  linux-image-lowlatency-lts-xenial  4.4.0.229.199
  linux-image-virtual-lts-xenial  4.4.0.229.199

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.
