CVE-2024-38607: macintosh/via-macii: Fix "BUG: sleeping function called from invalid context"

In the Linux kernel, the following vulnerability has been resolved: macintosh/via-macii: Fix "BUG: sleeping function called from invalid context" The via-macii ADB driver calls request_irq() after disabling hard interrupts. But disabling interrupts isn't necessary here because the VIA shift register interrupt was masked during VIA1 initialization.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel driver correctness issue in the Macintosh via-macii ADB driver. The driver could call a function that may sleep while interrupts were disabled, triggering a kernel BUG condition. The sources do not describe remote exploitation, privilege escalation, data theft, or active attacks.

Executive priority

Treat this as a low-priority kernel hygiene item unless the organization operates affected Macintosh-specific Linux systems. Include it in routine kernel updates and verify exposure before escalating operational urgency.

Technical view

The via-macii ADB driver called request_irq() after disabling hard interrupts. Because request_irq() may sleep, that creates an invalid-context BUG. The kernel fix notes interrupt disabling was unnecessary because the VIA shift register interrupt was already masked during VIA1 initialization.

Likely exposure

Exposure appears limited to Linux systems that build and use the macintosh/via-macii ADB driver on affected kernel versions. Typical server, cloud, and container fleets are unlikely to load this legacy Macintosh-specific driver, but kernel configuration should be verified.

Exploitation context

The bundle marks KEV as false and provides no cited evidence of active exploitation or public weaponization. The available description supports a stability or kernel-correctness concern, not a demonstrated remote attack path.

Researcher notes

Evidence is narrow: the source states the bug and fix rationale but does not provide CVSS, CWE, exploitability analysis, or impact beyond the BUG condition. Avoid assuming security impact beyond what kernel and CVE sources state.

Mitigation direction

  • Update affected Linux kernels using vendor or distribution guidance.
  • Confirm the relevant stable kernel fix is included in deployed builds.
  • If unused, avoid building or loading the via-macii ADB driver.
  • Prioritize normal kernel patch maintenance unless asset review shows exposure.

Validation and detection

  • Check kernel version and distribution advisory status for CVE-2024-38607.
  • Review kernel configuration for the macintosh/via-macii ADB driver.
  • Confirm deployed kernel source includes one of the referenced stable fixes.
  • Inspect logs for related invalid-context BUG messages on exposed systems.
