Ubuntu Security Notice USN-7179-2
January 06, 2025
linux-aws, linux-aws-5.15, linux-gcp, linux-gcp-5.15, linux-hwe-5.15,
linux-nvidia, linux-oracle, linux-raspi vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-nvidia: Linux kernel for NVIDIA systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems
- linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe-5.15: Linux hardware enablement (HWE) kernel
Details:
Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux
kernel contained a type-confusion error. A physically proximate remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2020-12351)
Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux
kernel did not properly initialize memory in some situations. A physically
proximate remote attacker could use this to expose sensitive information
(kernel memory). (CVE-2020-12352)
Andy Nguyen discovered that the Bluetooth HCI event packet parser in the
Linux kernel did not properly handle event advertisements of certain sizes,
leading to a heap-based buffer overflow. A physically proximate remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2020-24490)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- GPU drivers;
- Media drivers;
- Network drivers;
- SMB network file system;
- Bluetooth subsystem;
- Amateur Radio drivers;
- Network traffic control;
- VMware vSockets driver;
(CVE-2024-35963, CVE-2024-38553, CVE-2024-35965, CVE-2024-26822,
CVE-2024-35966, CVE-2024-53057, CVE-2024-43904, CVE-2024-50264,
CVE-2024-40973, CVE-2024-40910, CVE-2024-35967)

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.
