Detailsinfo

A vulnerability, which was classified as problematic, was found in Intel QuickAssist Technology Driver for Windows (version now known). Affected is some unknown processing. The manipulation with an unknown input leads to a use after free vulnerability. CWE is classifying the issue as CWE-416. The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. This is going to have an impact on integrity, and availability. CVE summarizes:

Use after free for some Intel(R) QuickAssist Technology Driver for Windows within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

The advisory is available at intel.com. This vulnerability is traded as CVE-2026-40427 since 04/15/2026. The exploitability is told to be easy. Local access is required to approach this attack.
