Ubuntu 22.04: USN-6150-1 Critical: Denial of Service Kernel Flaws

ubuntu
Calendar Grey June 8, 2023
Dist Ubuntu Esm H88
Numerous vulnerabilities within the Linux kernel for Ubuntu versions 20.04 and 22.04 have been identified and remedied. Discover more details.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-intel-iotg: Linux kernel for Intel IoT platforms

- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in

the netfilter subsystem of the Linux kernel when processing batch requests,

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-2023-32233)

Gwangun Jung discovered that the Quick Fair Queueing scheduler

implementation in the Linux kernel contained an out-of-bounds write

vulnerability. A local attacker could use this to cause a denial of service

(system crash) or possibly execute arbitrary code. (CVE-2023-31436)

Reima Ishii discovered that the nested KVM implementation for Intel x86

processors in the Linux kernel did not properly validate control registers

in certain situations. An ...

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-5.15.0-1030-raspi   5.15.0-1030.32
   linux-image-5.15.0-1030-raspi-nolpae  5.15.0-1030.32
   linux-image-5.15.0-1031-intel-iotg  5.15.0-1031.36
   linux-image-intel-iotg          5.15.0.1031.30
   linux-image-raspi               5.15.0.1030.27
   linux-image-raspi-nolpae        5.15.0.1030.27

Ubuntu 20.04 LTS:
   linux-image-5.4.0-1086-raspi    5.4.0-1086.97
   linux-image-raspi               5.4.0.1086.116
   linux-image-raspi2              5.4.0.1086.116

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.
