Ubuntu Security Notice USN-6973-3
August 26, 2024

linux-aws-5.4 vulnerabilities
==========================================================================

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

- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-aws-5.4: Linux kernel for Amazon Web Services (AWS) 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)

Update instructions:

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

Ubuntu 18.04 LTS
linux-image-5.4.0-1131-aws 5.4.0-1131.141~18.04.1
Available with Ubuntu Pro
linux-image-aws 5.4.0.1131.141~18.04.1
Available with Ubuntu Pro

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.
