Immediate attention is necessary for various security flaws in the Linux kernel affecting Ubuntu 23.04 and 22.04 LTS.
Several security issues were fixed in the Linux kernel.

Summary

A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.04 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-kvm: Linux kernel for cloud environments - linux-lowlatency: Linux low latency kernel - linux-raspi: Linux kernel for Raspberry Pi systems - linux-starfive: Linux kernel for StarFive processors - linux-aws-6.2: Linux kernel for Amazon Web Services (AWS) systems - linux-hwe-6.2: Linux hardware enablement (HWE) kernel - linux-lowlatency-hwe-6.2: Linux low latency kernel Details: Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. (CVE-2023-25775) Yu Hao disc...

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 23.04: linux-image-6.2.0-1009-starfive 6.2.0-1009.10 linux-image-6.2.0-1016-aws 6.2.0-1016.16 linux-image-6.2.0-1017-kvm 6.2.0-1017.17 linux-image-6.2.0-1017-lowlatency 6.2.0-1017.17 linux-image-6.2.0-1017-lowlatency-64k 6.2.0-1017.17 linux-image-6.2.0-1017-raspi 6.2.0-1017.19 linux-image-6.2.0-37-generic 6.2.0-37.38 linux-image-6.2.0-37-generic-64k 6.2.0-37.38 linux-image-6.2.0-37-generic-lpae 6.2.0-37.38 linux-image-aws 6.2.0.1016.17 linux-image-generic 6.2.0.37.37 linux-image-generic-64k 6.2.0.37.37 linux-image-generic-lpae 6.2.0.37.37 linux-image-kvm 6.2.0.1017.17 linux-image-lowlatency 6.2.0.1017.17 linux-image-lowlatency-64k 6.2.0.1017.17 linux-image-raspi 6.2.0.1017.20 linux-image-raspi-nolpae 6.2.0.1017.20 linux-image-starfive 6.2.0.1009.12 linux-image-virtual 6.2.0.37.37 Ubuntu 22.04 LTS: linux-image-6.2.0-1016-aws 6.2.0-1016.16~22.04.1 linux-image-6.2.0-1017-lowlatency 6.2.0-1017.17~22.04.1 linux-image-6.2.0-1017-lowlatency-64k 6.2.0-1017.17~22.04.1 linux-image-6.2.0-37-generic 6.2.0-37.38~22.04.1 linux-image-6.2.0-37-generic-64k 6.2.0-37.38~22.04.1 linux-image-6.2.0-37-generic-lpae 6.2.0-37.38~22.04.1 linux-image-aws 6.2.0.1016.16~22.04.1 linux-image-generic-64k-hwe-22.04 6.2.0.37.38~22.04.15 linux-image-generic-hwe-22.04 6.2.0.37.38~22.04.15 linux-image-generic-lpae-hwe-22.04 6.2.0.37.38~22.04.15 linux-image-lowlatency-64k-hwe-22.04 6.2.0.1017.17~22.04.14 linux-image-lowlatency-hwe-22.04 6.2.0.1017.17~22.04.14 linux-image-virtual-hwe-22.04 6.2.0.37.38~22.04.15 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.
