A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263) 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: - ARM64 architecture; - InfiniBand drivers; - Network drivers; - TCM subsystem; - exFAT file system; - Network file system (NFS) client; - Network file system (NFS) server daemon; - B.A.T.M.A.N. meshing protocol; - IPv4 networking; - IPv6 networking; - Netfilter; - RDS protocol; (CVE-2026-53186, CVE-2026-53216, CVE-2026-53221, CVE-2026-53354, CVE-2026-53355, CVE-2026-53398, CVE-2026-63800, CVE-2026-63808, CVE-2026-63887, CVE-2026-63888, CVE-2026-63912, CVE-2026-63922, CVE-2026-63924, CVE-2026-63984, CVE-2026-63992, CVE-2026-63993, CVE-2026-63994, CVE-2026-64007, CVE-2026-64091)
