Local denial of service via improper condition check
Published Jun 9, 2021 · Updated Aug 4, 2024
Improper condition checking in Intel Thunderbolt Controller firmware allows local users to cause denial of service through local access. Intel identifies affected firmware and controller models but does not disclose the checked condition, its code locus, or how local input reaches it. Exploitation requires low-privileged local access, and the documented consequence is loss of availability without confidentiality or integrity impact.
