========================================================================== Ubuntu Security Notice USN-7592-1 June 24, 2025 linux-aws-5.15, linux-gcp-5.15, linux-ibm-5.15, linux-lowlatency-hwe-5.15, linux-oracle-5.15 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems - linux-gcp-5.15: Linux kernel for Google Cloud Platform (GCP) systems - linux-ibm-5.15: Linux kernel for IBM cloud systems - linux-lowlatency-hwe-5.15: Linux low latency kernel - linux-oracle-5.15: Linux kernel for Oracle Cloud systems 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) 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) 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: - PowerPC architecture; - x86 architecture; - ACPI drivers; - Clock framework and drivers; - GPU drivers; - HID subsystem; - InfiniBand drivers; - Media drivers; - MemoryStick subsystem; - Network drivers; - Mellanox network drivers; - NTB driver; - PCI subsystem; - Voltage and Current Regulator drivers; - Remote Processor subsystem; - SCSI subsystem; - QCOM SoC drivers; - Thermal drivers; - BTRFS file system; - Ext4 file system; - JFS file system; - Network file system (NFS) server daemon; - NTFS3 file system; - File systems infrastructure; - Proc file system; - SMB network file system; - IPv6 networking; - RDMA verbs API; - SoC audio core drivers; - Tracing infrastructure; - Watch queue notification mechanism; - 802.1Q VLAN protocol; - Asynchronous Transfer Mode (ATM) subsystem; - Bluetooth subsystem; - Networking core; - IPv4 networking; - Netfilter; - Network traffic control; - SMC sockets; - Sun RPC protocol; - SoC Audio for Freescale CPUs drivers; (CVE-2025-22089, CVE-2025-22073, CVE-2025-23138, CVE-2025-21970, CVE-2025-21981, CVE-2025-22025, CVE-2025-39735, CVE-2025-22018, CVE-2025-21956, CVE-2025-39728, CVE-2024-46753, CVE-2024-58093, CVE-2025-37889, CVE-2025-22005, CVE-2025-22004, CVE-2025-21963, CVE-2025-21991, CVE-2024-56664, CVE-2025-22054, CVE-2024-46821, CVE-2023-53034, CVE-2022-49728, CVE-2025-22075, CVE-2025-21968, CVE-2025-22071, CVE-2025-22066, CVE-2025-22060, CVE-2024-46812, CVE-2025-22056, CVE-2025-22086, CVE-2022-49636, CVE-2025-21962, CVE-2025-38637, CVE-2025-22081, CVE-2025-21992, CVE-2024-42230, CVE-2025-21959, CVE-2024-53168, CVE-2025-38152, CVE-2025-22035, CVE-2025-21941, CVE-2025-22050, CVE-2025-21964, CVE-2025-22097, CVE-2025-22044, CVE-2025-22007, CVE-2025-21994, CVE-2025-22079, CVE-2024-56608, CVE-2025-37785, CVE-2025-22045, CVE-2025-22010, CVE-2024-36945, CVE-2025-21996, CVE-2025-22014, CVE-2025-21999, CVE-2025-21975, CVE-2025-22055, CVE-2025-21957, CVE-2025-37937, CVE-2025-38575, CVE-2025-22020, CVE-2025-22021, CVE-2024-53144, CVE-2025-22008, CVE-2025-22063, CVE-2024-56551, CVE-2025-23136) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.15.0-1078-ibm 5.15.0-1078.81~20.04.1 Available with Ubuntu Pro linux-image-5.15.0-1083-oracle 5.15.0-1083.89~20.04.1 Available with Ubuntu Pro linux-image-5.15.0-1085-gcp 5.15.0-1085.94~20.04.1 Available with Ubuntu Pro linux-image-5.15.0-1086-aws 5.15.0-1086.93~20.04.1 Available with Ubuntu Pro linux-image-5.15.0-142-lowlatency 5.15.0-142.152~20.04.1 Available with Ubuntu Pro linux-image-5.15.0-142-lowlatency-64k 5.15.0-142.152~20.04.1 Available with Ubuntu Pro linux-image-aws 5.15.0.1086.93~20.04.1 Available with Ubuntu Pro linux-image-gcp 5.15.0.1085.94~20.04.1 Available with Ubuntu Pro linux-image-ibm 5.15.0.1078.81~20.04.1 Available with Ubuntu Pro linux-image-lowlatency-64k-hwe-20.04 5.15.0.142.152~20.04.1 Available with Ubuntu Pro linux-image-lowlatency-hwe-20.04 5.15.0.142.152~20.04.1 Available with Ubuntu Pro linux-image-oracle 5.15.0.1083.89~20.04.1 Available with Ubuntu Pro 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.
