USN-7513-1: Linux kernel vulnerabilities
Publication date: 16 May 2025
Releases:24.04 LTS, 22.04 LTS

Overview

• Several security issues were fixed in the Linux kernel.

Packages

• linux - Linux kernel
• linux-aws - Linux kernel for Amazon Web Services (AWS) systems
• linux-aws-6.8 - Linux kernel for Amazon Web Services (AWS) systems
• linux-ibm - Linux kernel for IBM cloud systems
• linux-lowlatency - Linux low latency kernel
• linux-lowlatency-hwe-6.8 - Linux low latency kernel
• linux-oracle - Linux kernel for Oracle Cloud 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;

• EROFS file system;
• File systems infrastructure;
• Network file systems library;
• NILFS2 file system;
• Overlay file system;
• SMB network file system;
• VLANs driver;
