Ubuntu Security Notice USN-6688-1
March 11, 2024

linux-oem-6.1 vulnerabilities
==========================================================================

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

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-oem-6.1: Linux kernel for OEM systems

Details:

Pratyush Yadav discovered that the Xen network backend implementation in
the Linux kernel did not properly handle zero length data request, leading
to a null pointer dereference vulnerability. An attacker in a guest VM
could possibly use this to cause a denial of service (host domain crash).
(CVE-2023-46838)

It was discovered that the Habana's AI Processors driver in the Linux
kernel did not properly initialize certain data structures before passing
them to user space. A local attacker could use this to expose sensitive
information (kernel memory). (CVE-2023-50431)

Murray McAllister discovered that the VMware Virtual GPU DRM driver in the
Linux kernel did not properly handle memory objects when storing surfaces,
leading to a use-after-free vulnerability. A local attacker in a guest VM
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2023-5633)

It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly validate certain SMB messages, leading to an
out-of-bounds read vulnerability. An attacker could use this to cause a
denial of service (system crash) or possibly expose sensitive information.
(CVE-2023-6610)

It was discovered that the VirtIO subsystem in the Linux kernel did not
properly initialize memory in some situations. A local attacker could use
this to possibly expose sensitive information (kernel memory).
(CVE-2024-0340)

Lonial Con discovered that the netfilter subsystem in the Linux kernel did
not properly handle element deactivation in certain cases, 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-2024-1085)

Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, 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-2024-1086)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a null pointer dereference vulnerability. A
privileged local attacker could use this to possibly cause a denial of
service (system crash). (CVE-2024-24860)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:

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

Ubuntu 22.04 LTS:
   linux-image-6.1.0-1035-oem      6.1.0-1035.35
   linux-image-oem-22.04           6.1.0.1035.36
   linux-image-oem-22.04a          6.1.0.1035.36
   linux-image-oem-22.04b          6.1.0.1035.36
   linux-image-oem-22.04c          6.1.0.1035.36

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.
