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: - Cryptographic API; - Arm Firmware Framework for ARMv8-A(FFA); - Multiple devices driver; - Media drivers; - Network drivers; - NVDIMM (Non-Volatile Memory Device) drivers; - NVME drivers; - x86 platform drivers; - TCM subsystem; - Virtio drivers; - File systems infrastructure; - SMB network file system; - LZO compression library; - Digital Audio (PCM) driver; - Tracing infrastructure; - Padata parallel execution mechanism; - CAN network layer; - Networking core; - TIPC protocol; - ALSA framework; (CVE-2025-38079, CVE-2025-38048, CVE-2025-38075, CVE-2025-38077, CVE-2025-38035, CVE-2025-38037, CVE-2025-38034, CVE-2025-38058, CVE-2025-38004, CVE-2025-38031, CVE-2025-38078, CVE-2025-38044, CVE-2025-38066, CVE-2025-38052, CVE-2025-38043, CVE-2025-38065, CVE-2025-38003, CVE-2025-38061, CVE-2025-38051, CVE-2025-38072, CVE-2025-38068)
