[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7594-3 --- # USN-7594-3: Linux kernel vulnerabilities Publication date 8 July 2025 Overview Several security issues were fixed in the Linux kernel. Releases [25.04](https://ubuntu.com/security/notices?release=plucky) --- Open side navigation ## Packages * [linux-aws](https://ubuntu.com/security/cves?package=linux-aws) - Linux kernel for Amazon Web Services (AWS) systems * [linux-oracle](https://ubuntu.com/security/cves?package=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: * ARM32 architecture; * ARM64 architecture; * PowerPC architecture; * RISC-V architecture; * User-Mode Linux (UML); * x86 architecture; * Block layer subsystem; * Cryptographic API; * Compute Acceleration Framework; * ACPI drivers; * Serial ATA and Parallel ATA drivers; * Drivers core; * Ublk userspace block driver; * Bluetooth drivers; * Bus devices; * TPM device driver; * Clock framework and drivers; * CPU frequency scaling framework; * Buffer Sharing and Synchronization framework; * DMA engine subsystem; * GPU drivers; * HID subsystem; * HSI subsystem; * I2C subsystem; * I3C subsystem; * IIO... --- 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 | | --- | --- | | 25.04 plucky | [linux-image-6.14.0-1007-aws](https://launchpad.net/ubuntu/+source/linux-signed-aws) –  [6.14.0-1007.7](https://launchpad.net/ubuntu/+source/linux-signed-aws/6.14.0-1007.7) | | | | [linux-image-6.14.0-1007-aws-64k](https://launchpad.net/ubuntu/+source/linux-signed-aws) –  [6.14.0-1007.7](https://launchpad.net/ubuntu/+source/linux-signed-aws/6.14.0-1007.7) | | | | [linux-image-6.14.0-1007-oracle](https://launchpad.net/ubuntu/+source/linux-signed-oracle) –  [6.14.0-1007.7](https://launchpad.net/ubuntu/+source/linux-signed-oracle/6.14.0-1007.7) | | | | [linux-image-6.14.0-1007-oracle-64k](https://launchpad.net/ubuntu/+source/linux-signed-oracle) –  [6.14.0-1007.7](https://launchpad.net/ubuntu/+source/linux-signed-oracle/6.14.0-1007.7) | | | | [linux-image-aws](https://launchpad.net/ubuntu/+source/linux-meta-aws) –  [6.14.0-1007.7+1](https://launchpad.net/ubuntu/+source/linux-meta-aws/6.14.0-1007.7+1) | | | | [linux-image-aws-64k](https://launchpad.net/ubuntu/+source/linux-meta-aws) –  [6.14.0-1007.7+1](https://launchpad.net/ubuntu/+source/linux-meta-aws/6.14.0-1007.7+1) | | | | [linux-image-oracle](https://launchpad.net/ubuntu/+source/linux-meta-oracle) –  [6.14.0-1007.7](https://launchpad.net/ubuntu/+source/linux-meta-oracle/6.14.0-1007.7) | | | | [linux-image-oracle-64k](https://launchpad.net/ubuntu/+source/linux-meta-oracle) –  [6.14.0-1007.7](https://launchpad.net/ubuntu/+source/linux-meta-oracle/6.14.0-1007.7) | | | --- ### 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.
