memory security

The memory security tag covers reporting on vulnerabilities that expose or misuse information held in system memory. Current coverage focuses on CVE-2026-54116, a remotely reachable type confusion flaw in Microsoft SQL Server 2025 that can disclose internal memory pointers to an authenticated attacker over a network. The issue does not directly expose database rows, passwords, query contents, or customer files, but leaked addresses may weaken memory-layout protections and help support a follow-on exploit. This tag page provides context on the vulnerability, its security implications, Microsoft’s July 2026 disclosure, and the need to apply the relevant SQL Server security update.
