USN-8761-3: Linux kernel (Azure) vulnerabilities
Ubuntu patches Linux kernel vulnerabilities affecting Azure VMs across ARM, GPU, network, and file system subsystems.
Ubuntu published security notice USN-8761-3 addressing multiple vulnerabilities in the Linux kernel for Azure virtual machine environments. The update corrects security flaws across numerous subsystems including ARM32/ARM64/PowerPC architectures, compute acceleration framework, Bluetooth drivers, GPU drivers, InfiniBand drivers, network drivers, SCSI subsystem, Netfilter, and file system infrastructure. The advisory applies to Azure cloud environments and covers a broad range of kernel components.
- Ubuntu releases security update for Linux kernel Azure virtual machines.
- Patches address vulnerabilities across multiple architecture and driver subsystems.
- Fixes cover ARM, PowerPC, GPU, InfiniBand, Network, and SCSI subsystems.
- Additional patches for Bluetooth, Netfilter, and file system infrastructure.
- Advisory targets Azure cloud infrastructure environments.
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; - Compute Acceleration Framework; - Drivers core; - Bluetooth drivers; - Arm Firmware Framework for ARMv8-A(FFA); - EFI core; - GPU drivers; - Hardware monitoring drivers; - InfiniBand drivers; - Network drivers; - SCSI subsystem; - SPI subsystem; - Network file systems library; - NTFS3 file system; - SMB network file system; - File systems infrastructure; - Software nodes and device properties; - Bluetooth subsystem; - Netfilter; - Tracing…
