Ubuntu 20.04 LTS: USN-7194-1 critical: Bluetooth denial of service

ubuntu

January 9, 2025

Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-azure-5.15: Linux kernel for Microsoft Azure cloud systems

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

...

Update Instructions

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

Ubuntu 20.04 LTS
   linux-image-5.15.0-1078-azure   5.15.0-1078.87~20.04.1
   linux-image-azure               5.15.0.1078.87~20.04.1
   linux-image-azure-cvm           5.15.0.1078.87~20.04.1

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.
