Publication date: 18 August 2025
Overview: Several security issues were fixed in the Linux kernel.
Releases: 25.04 , 24.04 LTS

Packages

linux - Linux kernel
linux-aws - Linux kernel for Amazon Web Services (AWS) systems
linux-aws-6.14 - Linux kernel for Amazon Web Services (AWS) systems
linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
linux-gcp-6.14 - Linux kernel for Google Cloud Platform (GCP) systems

Details
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:

ARM64 architecture;
RISC-V architecture;
x86 architecture;
Buffer Sharing and Synchronization framework;
DMA engine subsystem;
GPU drivers;
HID subsystem;
IIO ADC drivers;
IIO subsystem;
InfiniBand drivers;
Input Device core drivers;
Network drivers;
Mellanox network drivers;
PHY drivers;
Voltage and Current Regulator drivers;
VideoCore services drivers;
USB Type-C Connector System Software Interface driver;
Xen hypervisor drivers;
EROFS file system;
Network file system (NFS) client;
File systems infrastructure;
SMB network file system;
Network traffic control;
io_uring subsystem;
Kernel command line parsing driver;
Scheduler infrastructure;
Memory management;
Networking core;
MAC80211 subsystem;
Management Component Transport Protocol (MCTP);
Netfilter;
Open vSwitch;
TLS protocol;
Wireless networking;
SOF drivers

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