Ubuntu Security Notice USN-6972-1
August 21, 2024<\/p>\n
linux, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
– linux: Linux kernel
– linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems
– linux-kvm: Linux kernel for cloud environments
– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
– linux-hwe: Linux hardware enablement (HWE) kernel<\/p>\n
Details:<\/p>\n
Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux
Kernel contained a race condition, leading to a NULL pointer dereference.
An attacker could possibly use this to cause a denial of service (system
crash). (CVE-2024-22099)<\/p>\n
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)<\/p>\n
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;
– User-Mode Linux (UML);
– GPU drivers;
– MMC subsystem;
– Network drivers;
– PHY drivers;
– Pin controllers subsystem;
– Xen hypervisor drivers;
– GFS2 file system;
– Core kernel;
– Bluetooth subsystem;
– IPv4 networking;

After a standard system update you need to reboot your computer to make
all the necessary changes.<\/p>\n
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.<\/p>\n
