[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7655-1 --- # USN-7655-1: Linux kernel (Intel IoTG) vulnerabilities Publication date 18 July 2025 Overview Several security issues were fixed in the Linux kernel. Releases [20.04 LTS](https://ubuntu.com/security/notices?release=focal) --- Open side navigation ## Packages * [linux-intel-iotg-5.15](https://ubuntu.com/security/cves?package=linux-intel-iotg-5.15) - Linux kernel for Intel IoT platforms ## Details Michael Randrianantenaina discovered that the Bluetooth driver in the Linux Kernel contained an improper access control vulnerability. A nearby attacker could use this to connect a rougue device and possibly execute arbitrary code. ([CVE-2024-8805](https://ubuntu.com/security/CVE-2024-8805)) It was discovered that the CIFS network file system implementation in the Linux kernel did not properly verify the target namespace when handling upcalls. An attacker could use this to expose sensitive information. ([CVE-2025-2312](https://ubuntu.com/security/CVE-2025-2312)) 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: * PA-RISC architecture; * PowerPC architecture; * x86 architecture; * Block layer subsystem; * Cryptographic API; * ACPI drivers; * Serial ATA and Parallel ATA... --- 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 | | --- | --- | | 20.04 LTS focal | [linux-image-5.15.0-1083-intel-iotg](https://launchpad.net/ubuntu/+source/linux-signed-intel-iotg-5.15) –  5.15.0-1083.89~20.04.1   Ubuntu Pro | | | | [linux-image-intel](https://launchpad.net/ubuntu/+source/linux-meta-intel-iotg-5.15) –  5.15.0.1083.89~20.04.1   Ubuntu Pro | | | | [linux-image-intel-iotg](https://launchpad.net/ubuntu/+source/linux-meta-intel-iotg-5.15) –  5.15.0.1083.89~20.04.1   Ubuntu Pro | | | | [linux-image-intel-iotg-5.15](https://launchpad.net/ubuntu/+source/linux-meta-intel-iotg-5.15) –  5.15.0.1083.89~20.04.1   Ubuntu Pro | | | --- ### 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.
