CVE-2026-20749: Escalation of Privilege in Intel(R) PROSet/Wireless WiFi Software
Out-of-bounds read for some Intel(R) PROSet/Wireless WiFi Software within Ring 2: Device Drivers may allow an escalation of privilege. Network adversary with an unauthenticated user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (low) impacts.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read in Intel(R) PROSet/Wireless WiFi Software device drivers (Ring 2), which may allow an unauthenticated network attacker with adjacent access to escalate privileges on the affected system. The attack complexity is low, and no user interaction is required. The vulnerability affects confidentiality and integrity at a low level, but availability impact is high. The CVSS 4.0 base score is 7.2, reflecting a high severity. No affected versions or patch information are provided, and no known exploits are reported in the wild.
Potential Impact
The vulnerability may allow an attacker to escalate privileges, potentially leading to partial compromise of system confidentiality and integrity, and a significant impact on system availability. The highest impact is on availability, which is rated high, while confidentiality and integrity impacts are low.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation recommendations are currently provided by the vendor. Monitor Intel's advisories for updates.
