USN-5977-1: Linux kernel (OEM) vulnerabilities
27 March 2023
Several security issues were fixed in the Linux kernel.
Reduce your security exposure
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and
Universe repositories, and it is free for up to five machines.

Releases
o Ubuntu 22.04 LTS
Packages
o linux-oem-6.0 - Linux kernel for OEM systems
Details
It was discovered that the network queuing discipline implementation 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-2023-1281 )
It was discovered that the KVM VMX implementation in the Linux kernel did
not properly handle indirect branch prediction isolation between L1 and L2
VMs. An attacker in a guest VM could use this to expose sensitive
information from the host OS or other guest VMs. ( CVE-2022-2196 )
Thadeu Cascardo discovered that the io_uring subsystem contained a double-
free vulnerability in certain memory allocation error conditions. A local
attacker could possibly use this to cause a denial of service (system
crash). ( CVE-2023-1032 )

Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 22.04
o linux-image-6.0.0-1013-oem - 6.0.0-1013.13
o linux-image-oem-22.04b - 6.0.0.1013.13
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.
