USN-7887-2: Linux kernel (Raspberry Pi) vulnerabilities

Publication date: 25 November 2025
Overview: Several security issues were fixed in the Linux kernel.

Packages

• linux-raspi - Linux kernel for Raspberry Pi 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;
• PowerPC architecture;
• x86 architecture;
• ACPI drivers;
• Ublk userspace block driver;
• Clock framework and drivers;
• EDAC drivers;
• GPU drivers;
• IIO subsystem;
• InfiniBand drivers;
• Media drivers;
• MemoryStick subsystem;
• Network drivers;
• NTB driver;
• PCI subsystem;
• Remote Processor subsystem;
• Thermal drivers;
• Virtio Host (VHOST) subsystem;
• 9P distributed file system;
• File systems infrastructure;
• JFS file system;
• Network file system (NFS) server daemon;
• NTFS3 file system;
• SMB network file system;
• Memory management;
• RDMA verbs API;
• Kernel fork() syscall;
• Tracing infrastructure;
• Watch queue notification mechanism;
• Asynchronous Transfer Mode (ATM) subsystem;
• Networking core;
• IPv4 networking;
• IPv6 networking;
• Netfilter;
• Network traffic control;
• SCTP protocol;
• TLS protocol;
• SoC Audio for Freescale CPUs drivers

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 LTS noble

• linux-image-6.8.0-1041-raspi – 6.8.0-1041.45
• linux-image-raspi – 6.8.0-1041.45
• linux-image-raspi-6.8 – 6.8.0-1041.45
