Key insight
Beyond the bare patch information, the report only clarifies that exploitation requires an authenticated attacker with network access to the SQL Server instance, making it primarily a privilege-escalation and lateral-movement vector inside the internal network , there is no indication of active exploitation or a public exploit.
Description
CVE-2026-67372 describes a heap-based buffer overflow in Microsoft SQL Server that allows an authorized attacker to execute code over the network. The flaw therefore requires valid credentials or an existing session on the database instance; unauthenticated external access is not a precondition according to the description. Affected are SQL Server installations reachable over the network whose database services are not restricted by network segmentation. The entry originates from the NVD and contains no information on active exploitation, proof-of-concept code, or inclusion in the CISA KEV list. A vendor-provided update is the only available remediation as of this report.
