CVE-2024-38607

Local service interruption via invalid interrupt context

Published Jun 19, 2024 · Updated May 11, 2026

A locking-context flaw in the Linux via-macii ADB driver allows local users to interrupt service on affected Macintosh systems. During driver initialization, via_init() disables hard interrupts before calling request_irq(), which can sleep, triggering a kernel BUG for an invalid atomic context. Exploitation requires local access to a system using the VIA Macintosh II ADB driver and can disrupt availability without disclosing or modifying data.
