security patching

About this tag
Security patching discussions on WindowsForum cover a range of vulnerabilities across Microsoft and Linux ecosystems, emphasizing the importance of timely updates. Topics include CVE-2026-47634 in SharePoint Server, CVE-2026-41095 in Windows Server Data Deduplication, and flaws in Windows Admin Center that highlight hybrid management risks. Linux kernel bugs such as CVE-2026-46149 (iSCSI sysfs over-read), CVE-2026-43619 (rsync symlink race), CVE-2026-43319 (spidev deadlock), CVE-2026-31570 (CAN gateway CRC8 OOB), and CVE-2026-31453 (XFS use-after-free) are also covered, often with implications for Windows-centric environments. The recurring theme is that security patching requires proactive attention to infrastructure-adjacent components, not just headline-grabbing exploits.
