CVE-2026-96956 Oct 13, 21:20 HIGH PATCH Exploit Unlikely This Week

Privilege elevation in Microsoft SQL Server lets an attacker who already holds high-privilege credentials on the instance trigger a stack-based buffer overflow over a network connection and break out of their authorization boundary. Exploitation is constrained: the CVSS vector (AV:N/AC:H/PR:H/UI:N/S:C) and the vendor description both indicate an authorized, highly privileged principal is required, and the AC:H rating means the overflow depends on specific server state, data, or timing rather than trivial input, so it is not reliably repeatable on a first attempt. All affected GDR and CU builds are pre-patch, Microsoft has published a fix via the MSRC update guide, and no public exploit or confirmed active exploitation was identified at time of analysis, so risk is real but conditional rather than a drop-everything emergency.

CVE-2026-94512 Oct 13, 21:19 HIGH PATCH This Week

Heap-based buffer overflow in Microsoft SQL Server lets an authenticated attacker who holds any valid, low-privileged database login - and can reach the instance's listening port over the network - execute code in the context of the SQL Server service process, with high confidentiality, integrity and availability impact (CVSS 8.8, PR:L, no user interaction). The vendor has released patched builds for SQL Server 2017, 2019, 2022 and 2025, and no public exploit code or confirmed active exploitation was identified at time of analysis, so this is a credible priority rather than an emergency. Because exploitation needs only ordinary credentials rather than sysadmin rights, the practical exposure is concentrated on instances reachable from untrusted networks and on estates where database logins are shared or weakly managed.

CVE-2026-88088 Oct 13, 21:19 HIGH PATCH This Week

Local privilege escalation in Microsoft SQL Server allows an authenticated attacker holding low-privilege access to the instance or its host to potentially elevate privileges on the underlying system by triggering an integer overflow (CWE-190). The assessed vector CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H (7.0 High) confirms the attack is local rather than network-based, requires a pre-existing authenticated foothold (PR:L), and carries high attack complexity (AC:H), meaning precise conditions such as specific input sizes or memory state are needed; no public exploit identified at time of analysis, and the issue is not in CISA KEV. This is a credible but not emergency-tier privilege-escalation issue whose practical risk concentrates on multi-tenant SQL Server instances or hosts shared with low-trust principals, and vendor patches are available per the Microsoft advisory.

CVE-2026-85886 Oct 13, 21:19 HIGH PATCH This Week

Heap-based buffer overflow in Microsoft SQL Server lets an attacker who already holds a valid low-privilege database login execute arbitrary code on the database engine over the network, with impact crossing a security scope boundary (CVSS 8.5; AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H). Affected builds span SQL Server 2017, 2019, 2022, and 2025 across both the GDR (security-only) and cumulative-update branches, so most unpatched enterprise estates that still run older builds are in scope. Exploitation is not trivial - the high attack complexity implies reliable heap layout/grooming or a timing-sensitive corruption window must be achieved - and there is no public exploit identified at time of analysis, but a vendor patch is available and the flaw should be prioritized on internet-exposed or broadly accessible database listeners.

Privilege elevation in Microsoft SQL Server (2017, 2019, 2022 and 2025 builds below their patched levels) allows an authenticated, low-privileged database principal to trigger a heap-based buffer overflow in the database engine over a network connection and gain higher privileges, with impact crossing a security boundary (CVSS 8.5, S:C). Exploitation is not anonymous: the attacker must already hold a valid SQL Server login (PR:L) and satisfy a hard-to-control heap-state or race condition (AC:H), so the flaw is not automatable or scalable (SSVC Automatable: no, Exploitation: none), and no public exploit code has been identified at time of analysis.

Deserialization of untrusted data in Microsoft SQL Server (SQL Server 2019, 2022, and 2025 GDR/CU builds) allows an attacker to achieve remote code execution with high confidentiality, integrity, and availability impact. Exploitation requires the attacker to already hold valid low-privilege authenticated access to the target instance (CVSS PR:L) plus network reachability (AV:N), with no user interaction (UI:N), so credential-less external attackers cannot exploit it directly; realistic risk concentrates on instances reachable by untrusted or lower-trust database users, such as multi-tenant applications, service accounts, or internal users. CISA's SSVC evaluation rates exploitation as none and automatable as no, and no public exploit code has been identified at time of analysis, but the technical impact is rated total.

An out-of-bounds read in Microsoft SQL Server exposes memory contents to unauthenticated attackers who can reach the server's database listener from an adjacent network segment. The flaw is rated CVSS 3.1 base 5.3 (AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N), so the disclosure is high-impact confidentiality only - there is no integrity or availability effect - and exploitability is constrained by High attack complexity, meaning success depends on server memory layout, timing, or state that the attacker cannot control, making the leak non-deterministic rather than reliably repeatable. Microsoft has published a fix through its update guide, and there is no public exploit code and no confirmed active exploitation (no POC, no CISA KEV; CISA SSVC records Exploitation: none).

An out-of-bounds read in Microsoft SQL Server exposes memory contents to unauthenticated attackers who can reach the server's database listener from an adjacent network segment. The flaw is rated CVSS 3.1 base 5.3 (AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N), so the disclosure is high-impact confidentiality only - there is no integrity or availability effect - and exploitability is constrained by High attack complexity, meaning success depends on server memory layout, timing, or state that the attacker cannot control, making the leak non-deterministic rather than reliably repeatable. Microsoft has published a fix through its update guide, and there is no public exploit code and no confirmed active exploitation (no POC, no CISA KEV; CISA SSVC records Exploitation: none).
