Microsoft has patched CVE-2026-68844, a heap-based buffer overflow in Windows Storage Spaces Controller rated CVSS 7.8 that lets authorized local attackers execute code. The fix ships in the September 2026 Patch Tuesday release covering nearly 1,000 vulnerabilities, with exploitation considered less likely.
The vulnerability allows an authorized attacker with low privileges to execute code locally on affected systems.
Exploitation is assessed as less likely, with no known public exploits or in-the-wild attacks reported.
Enterprise teams should treat this as routine Patch Tuesday hygiene given the low likelihood of exploitation, but verify Storage Spaces Controller usage on servers before deferring the update.
