6 January 2025
Several security issues were fixed in the Linux kernel.
Releases
Packages
- linux-aws - Linux kernel for Amazon Web Services (AWS) systems
- linux-kvm - Linux kernel for cloud environments
Details
Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux
kernel contained an integer overflow vulnerability. A local attacker could
use this to cause a denial of service (system crash). (CVE-2022-36402)
Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver
in the Linux kernel during device removal. A privileged attacker could use
this to cause a denial of service (system crash). (CVE-2023-35827)
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;
- I2C subsystem;
- Network drivers;
- Pin controllers subsystem;
- TTY drivers;
- USB Mass Storage drivers;
- Framebuffer layer;
- Ext4 file system;
- File systems infrastructure;
- Bluetooth subsystem;
- Kernel init infrastructure;
- DMA mapping infrastructure;
- Memory management;
- 9P file system network protocol;
- IPv4 networking;
- IPv6 networking;
- Logical Link layer;
- MAC80211 subsystem;
- Netfilter;
- NFC subsystem;
- Phonet protocol;
- Network traffic control;
- Wireless networking;

Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
linux-image-4.4.0-1140-kvm
-
4.4.0-1140.151
Available with Ubuntu Pro
-
linux-image-4.4.0-1177-aws
-
4.4.0-1177.192
Available with Ubuntu Pro
-
linux-image-aws
-
4.4.0.1177.181
Available with Ubuntu Pro
-
linux-image-kvm
-
4.4.0.1140.137
Available with Ubuntu Pro
Ubuntu 14.04
-
linux-image-4.4.0-1139-aws
-
4.4.0-1139.145
-
linux-image-aws
-
4.4.0.1139.136
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.
