Ubuntu 6973-1: Linux kernel Security Advisory Updates
Summary
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS - Ubuntu 18.04 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-azure: Linux kernel for Microsoft Azure Cloud systems - linux-bluefield: Linux kernel for NVIDIA BlueField platforms - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-gkeop: Linux kernel for Google Container Engine (GKE) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-kvm: Linux kernel for cloud environments - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-xilinx-zynqmp: Linux kernel for Xilinx ZynqMP processors - linux-gcp-5.4: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-5.4: Linux hardware enablement (HWE) kernel - linux-ibm-5.4: Linux kernel for IBM cloud systems - linux-oracle-5.4: Linux kernel for Oracle Cloud systems Details: It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-24860) 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: - SuperH RISC architecture; - MMC subsystem; - Network drivers; - SCSI drivers; - GFS2 file system; - IPv4 networking; - IPv6 networking; - HD-audio driver; (CVE-2024-26830, CVE-2024-39484, CVE-2024-36901, CVE-2024-26929, CVE-2024-26921, CVE-2021-46926, CVE-2023-52629, CVE-2023-52760)

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.
