Detailsinfo

A vulnerability was found in Linux Kernel up to 5.19.3. It has been classified as critical. Affected is an unknown function of the component ASoC. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot It is not yet clear, but it is possible to create a firmware so broken that it will send a reply message before a FW_READY message (it is not yet clear if FW_READY will arrive later). Since the reply_data is allocated only after the FW_READY message, this will lead to a NULL pointer dereference if not filtered out. The issue was reported with IPC4 firmware but the same condition is present for IPC3.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2022-50015 since 06/18/2025. The technical details are unknown and an exploit is not available.

Upgrading to version 5.19.4 eliminates this vulnerability. Applying the patch 48945246cf802b9866f3a821103f1a7a196baf68/499cc881b09c8283ab5e75b0d6d21cb427722161 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2025-1350). If you want to get best quality of vulnerability data, you may have to visit VulDB.
