It was discovered that a use-after-free vulnerability existed in the Bluetooth stack in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3640)
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: - SCSI subsystem; - Network file system (NFS) client; - NILFS2 file system; - File systems infrastructure; - Memory management; - Bluetooth subsystem; - Network traffic control; - USB sound devices; (CVE-2024-50116, CVE-2021-47576, CVE-2024-53197, CVE-2024-46787, CVE-2025-37798, CVE-2024-49958, CVE-2021-47260, CVE-2025-37932, CVE-2022-49909)
