CVE-2026-20714: Escalation of Privilege in Intel(R) QAT software drivers for Windows
Out-of-bounds write for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow a escalation of privilege. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable escalation of privilege. 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 (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AI Analysis
Technical Summary
This vulnerability is an out-of-bounds write in Intel(R) QAT software drivers for Windows prior to version 1.13, occurring in Ring 3 user applications. It allows a local, authenticated attacker with low complexity to escalate privileges. The CVSS 4.0 base score is 8.5, reflecting high impact on confidentiality, integrity, and availability. The vulnerability does not require user interaction and does not involve special internal knowledge. No vendor advisory or patch information is currently available.
Potential Impact
If exploited, this vulnerability could allow an authenticated local user with limited privileges to gain elevated privileges on the affected system. This escalation could compromise system confidentiality, integrity, and availability at a high level. There are no reported impacts on system confidentiality, integrity, or availability beyond the escalation itself. No known exploits are currently reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to systems running vulnerable versions of Intel(R) QAT software drivers to trusted users only. Monitor for updates from Intel regarding patches or workarounds.
