Multiple vulnerabilities (CVE-2021-47599, CVSS 4.7; CVE-2022-48875, CVSS 5.5; CVE-2022-49267, CVSS 7.8) affect core Linux kernel subsystems including x86 architecture, network drivers, filesystems, and the MAC framework, potentially allowing system compromise. Affected versions include linux_kernel < 5.15.11 for CVE-2021-47599, linux_kernel < 5.10.165, >= 5.11 < 5.15.90, and >= 5.16 < 6.1.8 for CVE-2022-48875, and linux_kernel < 5.16.19 and >= 5.17 < 5.17.2 for CVE-2022-49267. The fixed versions are 5.15.11, 5.10.165/5.15.90/6.1.8, and 5.16.19/5.17.2 respectively.
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: - x86 architecture; - MMC subsystem; - Network drivers; - USB Device Class drivers; - BTRFS file system; - HFS+ file system; - XFRM subsystem; - IPv4 networking; - IPv6 networking; - MAC80211 subsystem; - Simplified Mandatory Access Control Kernel framework; (CVE-2021-47599, CVE-2022-48875, CVE-2022-49267, CVE-2024-47659, CVE-2024-49927, CVE-2024-56548, CVE-2024-56581, CVE-2024-56593, CVE-2025-21704, CVE-2025-40215)
