Description OSIDB Bzimport 2026-11-10 20:08:44 UTC 
Stack-based buffer overflow for some Intel(R) Wireless Bluetooth(R) within Ring 0: Kernel may allow a denial of service. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are 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.
