vulnerabilities
==========================================================================

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

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-azure: Linux kernel for Microsoft Azure Cloud 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-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-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) 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

Details:

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.
This update corrects flaws in the following subsystems:
   - SuperH RISC architecture;
   - MMC subsystem;
   - Network drivers;
   - SCSI drivers;
   - GFS2 file system;
   - IPv4 networking;
   - IPv6 networking;
   - HD-audio driver;
(CVE-2024-26830, CVE-2024-39484, CVE-2024-36901, CVE-2024-26929,
CVE-2024-26921, CVE-2021-46926, CVE-2023-52629, CVE-2023-52760)

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.
