Short explanation
CVE-2026-101310 affects the bhyve HDA audio device model due to missing checks for zero-length Buffer Descriptor List entries when starting a stream. This causes out-of-bounds read or write during DMA transfer processing. A malicious guest can crash the bhyve process or execute arbitrary code.
This vulnerability compromises virtualization security because it can lead to code execution within the host userspace context running the virtual machine or cause process crashes, though subject to bhyve's Capsicum sandbox.
What should be done?
- Follow official vendor advisories.
- Check the patch status for affected versions.
- Apply necessary updates.
Chain of evidence and sources
HDA ses cihazı modeli, bir akış başlatılırken sıfır uzunluklu Tampon Tanımlayıcı Listesi girdilerini kontrol etmemektedir.
Kötü niyetli bir konuk bhyve sürecini çökertebilir veya konak kullanıcı alanı bağlamında rastgele kod çalıştırabilir.

Show the technical text from the sources
The HDA audio device model did not check for zero-length Buffer Descriptor List (BDL) entries when starting a stream. A zero-length entry caused an out-of-bounds read or write during DMA transfer processing. BDL fields were also subject to modification by the guest after validation. A malicious guest can crash the bhyve process or potentially execute arbitrary code in the host userspace context running the virtual machine, subject to bhyve's Capsicum sandbox.
