USN-6520-1 --- # USN-6520-1: Linux kernel (StarFive) vulnerabilities Publication date 28 November 2023 Overview Several security issues were fixed in the Linux kernel. Releases [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) --- Open side navigation ## Packages * [linux-starfive-6.2](https://ubuntu.com/security/cves?package=linux-starfive-6.2) - Linux kernel for StarFive processors ## 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](https://ubuntu.com/security/CVE-2023-25775)) Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). ([CVE-2023-31083](https://ubuntu.com/security/CVE-2023-31083)) Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service (system crash). ([CVE-2023-31085](https://ubuntu.com/security/CVE-2023-31085)) Lin Ma discovered that the... --- Show more ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) 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. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 22.04 LTS jammy | [linux-image-6.2.0-1009-starfive](https://launchpad.net/ubuntu/+source/linux-starfive-6.2) –  [6.2.0-1009.10~22.04.1](https://launchpad.net/ubuntu/+source/linux-starfive-6.2/6.2.0-1009.10~22.04.1) | | | | [linux-image-starfive](https://launchpad.net/ubuntu/+source/linux-meta-starfive-6.2) –  [6.2.0.1009.10~22.04.2](https://launchpad.net/ubuntu/+source/linux-meta-starfive-6.2/6.2.0.1009.10~22.04.2) | | | --- ### Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
