Ubuntu Security Notice USN-6648-1

Ubuntu Security Notice USN-6648-1
Posted Feb 22, 2024
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 6648-1 - It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service.

==========================================================================

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-bluefield: Linux kernel for NVIDIA BlueField platforms
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-gkeop: Linux kernel for Google Container Engine (GKE) systems
- linux-ibm: Linux kernel for IBM cloud systems
- linux-iot: Linux kernel for IoT platforms
- linux-kvm: Linux kernel for cloud environments
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors
- linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) systems
- linux-hwe-5.4: Linux hardware enablement (HWE) kernel
- linux-ibm-5.4: Linux kernel for IBM cloud systems
- linux-oracle-5.4: Linux kernel for Oracle Cloud systems
- linux-raspi-5.4: Linux kernel for Raspberry Pi systems

Details:

It was discovered that a race condition existed in the AppleTalk networking
subsystem of the Linux kernel, 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-2023-51781)

Zhenghan Wang discovered that the generic ID allocator implementation in
the Linux kernel did not properly check for null bitmap when releasing IDs.
A local attacker could use this to cause a denial of service (system
crash). (CVE-2023-6915)

Robert Morris discovered that the CIFS network file system implementation
in the Linux kernel did not properly validate certain server commands
fields, 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-2024-0565)

Jann Horn discovered that the TLS subsystem in the Linux kernel did not
properly handle spliced messages, 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-2024-0646)

Update instructions:

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.
