Vulnerability from osv_ubuntu – Published: 2024-05-21 16:15 – Updated: 2026-10-28 04:32 – Source websiteIn the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix possible null-ptr-deref when assigning a stream While AudioDSP drivers assign streams exclusively of HOST or LINK type, nothing blocks a user to attempt to assign a COUPLED stream. As supplied substream instance may be a stub, what is the case when code-loading, such scenario ends with null-ptr-deref.

"priority_reason": "The vulnerability depends on a stub substream with NULL pcm pointer reaching snd_hdac_stream_assign via COUPLED type, but no existing kernel code path produces this condition from userspace. All stub substream callers use HOST type and all COUPLED callers pass real substreams with non-NULL pcm, making the bug not reliably triggerable."

"priority_reason": "The vulnerability depends on a stub substream with NULL pcm pointer reaching snd_hdac_stream_assign via COUPLED type, but no existing kernel code path produces this condition from userspace. All stub substream callers use HOST type and all COUPLED callers pass real substreams with non-NULL pcm, making the bug not reliably triggerable."

"priority_reason": "The vulnerability depends on a stub substream with NULL pcm pointer reaching snd_hdac_stream_assign via COUPLED type, but no existing kernel code path produces this condition from userspace. All stub substream callers use HOST type and all COUPLED callers pass real substreams with non-NULL pcm, making the bug not reliably triggerable."

"priority_reason": "The vulnerability depends on a stub substream with NULL pcm pointer reaching snd_hdac_stream_assign via COUPLED type, but no existing kernel code path produces this condition from userspace. All stub substream callers use HOST type and all COUPLED callers pass real substreams with non-NULL pcm, making the bug not reliably triggerable."

"priority_reason": "The vulnerability depends on a stub substream with NULL pcm pointer reaching snd_hdac_stream_assign via COUPLED type, but no existing kernel code path produces this condition from userspace. All stub substream callers use HOST type and all COUPLED callers pass real substreams with non-NULL pcm, making the bug not reliably triggerable."
