Ubuntu 22.04 LTS USN-5599-1 Critical: Oracle Kernel Denial of Service

ubuntu
Calendar Grey September 5, 2022
Dist Ubuntu Esm H88
Patch released to address several vulnerabilities in the Ubuntu Linux kernel tailored for Oracle environments. Upgrade promptly to safeguard against potential risks.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-oracle: Linux kernel for Oracle Cloud systems

Details:

Asaf Modelevsky discovered that the Intel(R) 10GbE PCI Express (ixgbe)

Ethernet driver for the Linux kernel performed insufficient control flow

management. A local attacker could possibly use this to cause a denial

of service. (CVE-2021-33061)

It was discovered that the IP implementation in the Linux kernel did not

provide sufficient randomization when calculating port offsets. An

attacker could possibly use this to expose sensitive information.

(CVE-2022-1012)

Norbert Slusarek discovered that a race condition existed in the perf

subsystem in the Linux kernel, resulting in a use-after-free

vulnerability. A privileged local attacker could use this to cause a

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

(CVE-2022-1729)

Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM

Update Instructions

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

Ubuntu 22.04 LTS:
   linux-image-5.15.0-1017-oracle  5.15.0-1017.22
   linux-image-oracle              5.15.0.1017.15

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.
