USN-7513-2: Linux kernel (Real-time) vulnerabilities
Publication date

16 May 2025

Overview

Several security issues were fixed in the Linux kernel.

Releases: 24.04 LTS

Packages
linux-realtime - Linux kernel for Real-time 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:

RISC-V architecture;
x86 architecture;
Block layer subsystem;
Compute Acceleration Framework;
ACPI drivers;
Drivers core;
Ublk userspace block driver;
Virtio block driver;
DMA engine subsystem;
GPU drivers;
Microsoft Hyper-V drivers;
Hardware monitoring drivers;
IIO ADC drivers;
IIO subsystem;
InfiniBand drivers;
Multiple devices driver;
Media drivers;
Microchip PCI driver;
Network drivers;
Mellanox network drivers;
STMicroelectronics network drivers;
PCI subsystem;
Pin controllers subsystem;
x86 platform drivers;
Power supply drivers;

EROFS file system;
File systems infrastructure;
Network file systems library;
NILFS2 file system;
Overlay file system;
SMB network file system;
VLANs driver;
Memory management;
LAPB network protocol;
io_uring subsystem;
BPF subsystem;
Control group (cgroup);
Tracing infrastructure;
Workqueue subsystem;
Bluetooth subsystem;
Networking core;

Update instructions
After a standard system update you need to reboot your computer to make all the necessary changes.

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

24.04 noble
linux-image-6.8.1-1022-realtime – 6.8.1-1022.23
linux-image-realtime – 6.8.1-1022.23
