Ubuntu Security Notice USN-5381-1
Posted Apr 21, 2022
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5381-1 - David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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.

linux-oem-5.14 vulnerabilities
==========================================================================

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

- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-oem-5.14: Linux kernel for OEM systems

Details:

David Bouman discovered that the netfilter subsystem in the Linux kernel
did not properly validate passed user register indices. A local attacker
could use this to cause a denial of service or possibly execute arbitrary
code. (CVE-2022-1015)

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)

It was discovered that the DMA subsystem in the Linux kernel did not
properly ensure bounce buffers were completely overwritten by the DMA
device. A local attacker could use this to expose sensitive information
(kernel memory). (CVE-2022-0854)

Jann Horn discovered that the FUSE file system 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-2022-1011)

David Bouman discovered that the netfilter subsystem in the Linux kernel
did not initialize memory in some situations. A local attacker could use
this to expose sensitive information (kernel memory). (CVE-2022-1016)

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 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)

It was discovered that the ST21NFCA NFC driver in the Linux kernel
did not properly validate the size of certain data in EVT_TRANSACTION
events. A physically proximate attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-26490)

It was discovered that the USB SR9700 ethernet device driver for the
Linux kernel did not properly validate the length of requests from
the device. A physically proximate attacker could possibly use this
to expose sensitive information (kernel memory). (CVE-2022-26966)

It was discovered that the Xilinx USB2 device gadget driver in the
Linux kernel did not properly validate endpoint indices from the
host. A physically proximate attacker could possibly use this to
cause a denial of service (system crash). (CVE-2022-27223)

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)

Update instructions:

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

Ubuntu 20.04 LTS:
linux-image-5.14.0-1033-oem 5.14.0-1033.36
linux-image-oem-20.04 5.14.0.1033.30
linux-image-oem-20.04b 5.14.0.1033.30
linux-image-oem-20.04c 5.14.0.1033.30
linux-image-oem-20.04d 5.14.0.1033.30

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.
