CVE-2023-26586

Adjacent service interruption via uncaught exception

Published Feb 14, 2024 · Updated Aug 14, 2024

An uncaught exception in Intel Wi-Fi software allows physically proximate attackers to interrupt service through adjacent wireless access. Intel identifies the weakness but does not disclose the affected code path, triggering input, or exception that escapes handling. Exploitation requires adjacent wireless access and no authentication; the documented consequence is limited to reduced availability.
