Ubuntu Security Notice USN-5295-2
February 22, 2022

linux, linux-aws, linux-gcp, linux-kvm, linux-oracle, linux-raspi
vulnerabilities
==========================================================================

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

- Ubuntu 21.10

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-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

It was discovered that the Packet network protocol implementation in the
Linux kernel contained a double-free vulnerability. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2021-22600)

Jann Horn discovered a race condition in the Unix domain socket
implementation in the Linux kernel that could result in a read-after-free.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2021-4083)

Kirill Tkhai discovered that the XFS file system implementation in the
Linux kernel did not calculate size correctly when pre-allocating space in
some situations. A local attacker could use this to expose sensitive
information. (CVE-2021-4155)

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 VMware Virtual GPU driver in the Linux kernel
did not properly handle certain failure conditions, leading to a stale
entry in the file descriptor table. A local attacker could use this to
expose sensitive information or possibly gain administrative privileges.
(CVE-2022-22942)

Update instructions:

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

Ubuntu 21.10:
linux-image-5.13.0-1013-kvm 5.13.0-1013.14
linux-image-5.13.0-1015-gcp 5.13.0-1015.18
linux-image-5.13.0-1017-raspi 5.13.0-1017.19
linux-image-5.13.0-1017-raspi-nolpae 5.13.0-1017.19
linux-image-5.13.0-1018-oracle 5.13.0-1018.22
linux-image-5.13.0-30-generic 5.13.0-30.33
linux-image-5.13.0-30-generic-64k 5.13.0-30.33
linux-image-5.13.0-30-generic-lpae 5.13.0-30.33
linux-image-5.13.0-30-lowlatency 5.13.0-30.33
linux-image-aws 5.13.0.1014.15
linux-image-gcp 5.13.0.1015.14
linux-image-generic 5.13.0.30.40
linux-image-generic-64k 5.13.0.30.40
linux-image-generic-lpae 5.13.0.30.40
linux-image-gke 5.13.0.1015.14
linux-image-kvm 5.13.0.1013.13
linux-image-lowlatency 5.13.0.30.40
linux-image-oem-20.04 5.13.0.30.40
linux-image-oracle 5.13.0.1018.18
linux-image-raspi 5.13.0.1017.22
linux-image-raspi-nolpae 5.13.0.1017.22
linux-image-virtual 5.13.0.30.40

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.

Ubuntu Security Notice USN-5299-1
February 22, 2022

linux, linux-aws, linux-kvm, linux-lts-xenial 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: Linux kernel

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-kvm: Linux kernel for cloud environments

- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

reassemble mixed encrypted and plaintext fragments. A physically proximate
attacker could possibly use this issue to inject packets or exfiltrate
selected fragments. (CVE-2020-26147)

It was discovered that the bluetooth subsystem in the Linux kernel did not
properly perform access control. An authenticated attacker could possibly
use this to expose sensitive information. (CVE-2020-26558, CVE-2021-0129)

It was discovered that the RPA PCI Hotplug driver implementation in the
Linux kernel did not properly handle device name writes via sysfs, leading
to a buffer overflow. A privileged attacker could use this to cause a

denial of service (system crash) or possibly execute arbitrary code.

(CVE-2021-28972)

It was discovered that a use-after-free existed in the Bluetooth HCI driver
of the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2021-33034)

Norbert Slusarek discovered that the CAN broadcast manger (bcm) protocol
implementation in the Linux kernel did not properly initialize memory in

some situations. A local attacker could use this to expose sensitive

information (kernel memory). (CVE-2021-34693)

马哲宇 discovered that the IEEE 1394 (Firewire) nosy packet sniffer driver in
the Linux kernel did not properly perform reference counting 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-2021-3483)

It was discovered that the bluetooth subsystem in the Linux kernel did not
properly handle HCI device initialization failure, leading to a double-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2021-3564)

Murray McAllister discovered that the joystick device interface in the
Linux kernel did not properly validate data passed via an ioctl(). A local

attacker could use this to cause a denial of service (system crash) or

possibly execute arbitrary code on systems with a joystick device
registered. (CVE-2021-3612)

It was discovered that the tracing subsystem in the Linux kernel did not
properly keep track of per-cpu ring buffer state. A privileged attacker
could use this to cause a denial of service. (CVE-2021-3679)

It was discovered that the MAX-3421 host USB device driver in the Linux
kernel did not properly handle device removal events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2021-38204)

It was discovered that the 6pack network protocol driver in the Linux
kernel did not properly perform validation checks. A privileged attacker
could use this to cause a denial of service (system crash) or execute
arbitrary code. (CVE-2021-42008)

Amit Klein discovered that the IPv6 implementation in the Linux kernel
could disclose internal state in some situations. An attacker could
possibly use this to expose sensitive information. (CVE-2021-45485)

arbitrary code. (CVE-2021-22600)

Jürgen Groß discovered that the Xen subsystem within the Linux kernel did
not adequately limit the number of events driver domains (unprivileged PV
backends) could send to other guest VMs. An attacker in a driver domain
could use this to cause a denial of service in other guest VMs.
(CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

Jürgen Groß discovered that the Xen network backend driver in the Linux
kernel did not adequately limit the amount of queued packets when a guest
did not process them. An attacker in a guest VM can use this to cause a
denial of service (excessive kernel memory consumption) in the network
backend domain. (CVE-2021-28714, CVE-2021-28715)

Szymon Heidrich discovered that the USB Gadget subsystem in the Linux
kernel did not properly restrict the size of control requests for certain

possibly execute arbitrary code. (CVE-2021-39685)

Jann Horn discovered a race condition in the Unix domain socket
implementation in the Linux kernel that could result in a read-after-free.

A local attacker could use this to cause a denial of service (system crash)

or possibly execute arbitrary code. (CVE-2021-4083)
