Description

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.

Affected products

• Linux kernel: from 6.3 before 6.6.80; from 6.7 before 6.12.17; from 6.13 before 6.13.5; 6.14-rc1, 6.14-rc2, 6.14-rc3 — fixed in 6.12.17, 6.13.5, 6.6.80
