Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Microsoft SQL Server Native Scoring is affected by CVE-2024-26191, a remote code execution vulnerability disclosed on 2024-09-10. The flaw carries a CVSS 3.1 base score of 8.8 and is associated with CWE-122, indicating a heap-based buffer overflow condition within the native scoring component.

An attacker with low privileges can exploit the issue over the network without user interaction. Successful exploitation grants the ability to execute arbitrary code, resulting in full compromise of confidentiality, integrity, and availability on the affected SQL Server instance.

The official Microsoft Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-26191 describes available patches and mitigation steps. The associated EPSS score reached a modest peak of 0.0517 before receding to its current value of 0.0409, indicating limited post-disclosure exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including fuzzing and memory-error detectors) can discover heap overflows after they have been coded.

Input validation enforces bounds checking on data written to heap buffers, directly stopping the overflow condition from being introduced.

Security engineering principles require use of memory-safe constructs and bounds-checked allocation routines that avoid introducing heap overflows.

Memory-protection mechanisms limit the ability of a heap overflow to execute attacker-controlled code or corrupt adjacent structures.
