This USN-8527-1 advisory details multiple vulnerabilities across numerous Linux kernel subsystems, including networking, file systems, drivers, and core infrastructure, which could allow an attacker to compromise the system. The provided NVD data for three example CVEs (CVE-2022-48816, CVE-2023-53673, CVE-2025-37778) shows affected version ranges spanning multiple kernel series, with specific fixed versions provided for each (e.g., CVE-2023-53673 is fixed in 5.15.200, 6.1.42, and 6.4.7). Due to the broad scope and large number of distinct CVEs, IT professionals must consult the full advisory and NVD entries for each CVE to determine their specific exposure and required patching actions.
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: - RISC-V architecture; - Cryptographic API; - InfiniBand drivers; - IOMMU subsystem; - Network drivers; - STMicroelectronics network drivers; - NVME drivers; - x86 platform drivers; - SCSI subsystem; - SPI subsystem; - TCM subsystem; - USB over IP driver; - File systems infrastructure; - HFS+ file system; - Network file system (NFS) server daemon; - SMB network file system; - IPv6 networking; - Tracing infrastructure; - Timer subsystem; - B.A.T.M.A.N. meshing protocol; - Bluetooth subsystem; - Ethernet bridge; - Ceph Core library; - IPv4 networking; - MAC80211 subsystem; - Multipath TCP; - Netfilter; - RxRPC session sockets; - SMC sockets; - Sun RPC protocol; - X.25 network layer; - AMD SoC Alsa drivers; - KVM subsystem; (CVE-2022-48816, CVE-2023-53673, CVE-2025-37778, CVE-2025-37822, CVE-2025-37924, CVE-2025-38201, CVE-2025-40082, CVE-2025-68214, CVE-2025-68263, CVE-2025-71089, CVE-2025-71220, CVE-2025-71222, CVE-2025-71224, CVE-2026-23176, CVE-2026-23180, CVE-2026-23182, CVE-2026-23190, CVE-2026-23193, CVE-2026-23198, CVE-2026-23202, CVE-2026-23206, CVE-2026-23216, CVE-2026-23256, CVE-2026-23257, CVE-2026-23258, CVE-2026-23262, CVE-2026-23272, CVE-2026-23278, CVE-2026-23428, CVE-2026-23450, CVE-2026-23455, CVE-2026-31402, CVE-2026-31418, CVE-2026-31478, CVE-2026-31607, CVE-2026-31637, CVE-2026-31649, CVE-2026-31657, CVE-2026-31659, CVE-2026-31668, CVE-2026-31669, CVE-2026-31682, CVE-2026-31685, CVE-2026-43011, CVE-2026-43037, CVE-2026-43038, CVE-2026-43071, CVE-2026-43114, CVE-2026-43117, CVE-2026-43186, CVE-2026-43304, CVE-2026-43341, CVE-2026-43383, CVE-2026-43406, CVE-2026-43407, CVE-2026-43414, CVE-2026-43493, CVE-2026-43501, CVE-2026-45988, CVE-2026-46043, CVE-2026-46119, CVE-2026-46135, CVE-2026-46195, CVE-2026-46243)
