Vulnerability from github – Published: 2025-03-12 12:30 – Updated: 2026-06-01 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()

The nullity of sps->cstream should be checked similarly as it is done in sof_set_stream_data_offset() function. Assuming that it is not NULL if sps->stream is NULL is incorrect and can lead to NULL pointer dereference.

Severity

5.5 (Medium)
