Ubuntu Security Notice USN-6548-3
December 13, 2023

linux-oracle 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-oracle: Linux kernel for Oracle Cloud systems

Details:

It was discovered that Spectre-BHB mitigations were missing for Ampere
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2023-3006)

It was discovered that the USB subsystem in the Linux kernel contained a
race condition while handling device descriptors in certain situations,
leading to a out-of-bounds read vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2023-37453)

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did
not properly validate some attributes passed from userspace. A local
attacker could use this to cause a denial of service (system crash) or
possibly expose sensitive information (kernel memory). (CVE-2023-39189)

Sunjoo Park discovered that the netfilter subsystem in the Linux kernel did
not properly validate u32 packets content, leading to an out-of-bounds read
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-39192)

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did
not properly validate SCTP data, leading to an out-of-bounds read
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-39193)

Lucas Leong discovered that the Netlink Transformation (XFRM) subsystem in
the Linux kernel did not properly handle state filters, leading to an out-
of-bounds read vulnerability. A privileged local attacker could use this to
cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2023-39194)

Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did
not properly handle socket buffers (skb) when performing IP routing in
certain circumstances, leading to a null pointer dereference vulnerability.
A privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-42754)

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly handle queue initialization failures in certain
situations, leading to a use-after-free vulnerability. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-5178)

Budimir Markovic discovered that the perf subsystem in the Linux kernel did
not properly handle event groups, leading to 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-2023-5717)

It was discovered that the TLS subsystem in the Linux kernel did not
properly perform cryptographic operations in some situations, leading to a
null pointer dereference vulnerability. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-6176)

Update instructions:

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

Ubuntu 20.04 LTS:
linux-image-5.4.0-1115-oracle 5.4.0-1115.124
linux-image-oracle-lts-20.04 5.4.0.1115.108

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.
