Intel Wireless Bluetooth: Use after free in kernel driver allows denial of service

CVE-2026-44625Medium 6.8

← All vulnerabilities

Summary

Some Intel Wireless Bluetooth drivers and software packages for Windows contain a use-after-free flaw (CWE-416) in a Ring 0 kernel component. A local attacker with an authenticated low-privileged account can trigger a system crash and thus a denial of service. No confidentiality or integrity impact is expected according to the CVSS vector, and no user interaction is required.

Affected

  • Intel Wireless Bluetooth drivers and software for Windows (affected versions: Unknown, Intel advisory INTEL-SA-01530 could not be verified)

Fixed in

  • Unknown for this CVE. Intel recommends the newest Intel Wireless Bluetooth package (24.80.0 is listed on Intel's download page). Verify the fixed versions in INTEL-SA-01530.

Workaround

  • No vendor-specific workaround found.
  • Where Bluetooth is not required, disable the Bluetooth adapter via policy.
  • Secondary sources suggest restricting local user privileges (not vendor guidance).

Exploitation

  • Not known to be exploited according to secondary aggregators. No public proof of concept indexed. Nothing found in CISA KEV at the time of research.

Our recommendation

  • Open Intel advisory INTEL-SA-01530 and confirm the affected and fixed versions.
  • Deploy the newest Intel Wireless Bluetooth package via vendor or patch tool, together with the related batch CVEs (for example CVE-2026-44382 and CVE-2026-42956).
  • Verify driver versions across the fleet, with priority on shared endpoints, kiosks and terminal servers.
  • Re-check NVD and CISA KEV, since NVD analysis is pending.

Public exploits

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)

Use after free for some Intel(R) Wireless Bluetooth(R) 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.
