Summary:
Potential security vulnerabilities in some Intel® PROSet/Wireless WiFi and Intel® Wireless Bluetooth® products may allow denial of service, or escalation of privilege. Intel is releasing firmware and software updates to mitigate these potential vulnerabilities.
Vulnerability Details:
CVEID: CVE-2026-40433
Description: Heap-based buffer overflow for some Intel® PROSet Wireless Wi-Fi Software for Windows within Ring 0: Kernel may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent network 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 (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (high) impacts.
CVSS Base Score 4.0: 8.5 High
CVSS Vector 4.0: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H
CVEID: CVE-2026-40626
Description: Uncontrolled search path for some Intel® Wireless Bluetooth® software for Windows within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active 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.
CVSS Base Score 4.0: 5.4 Medium

CVEID: CVE-2026-40695
Description: Null pointer dereference for some Intel® Wireless Bluetooth® within Ring 0: Kernel 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 (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
CVSS Base Score 4.0: 6.8 Medium

Description: Use after free for some Intel® Wireless Software for Windows within Ring 3: User Applications may allow denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are 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 (low) and availability (low) impacts.
