Linux Kernel NULL Pointer Dereference Vulnerability in ASoC SOF Stream IPC

A vulnerability in the Linux kernel's ASoC SOF stream IPC component can lead to a NULL pointer dereference. The issue arises because the nullity of the 'cstream' variable is not properly checked, similar to the validation performed in the 'sof_set_stream_data_offset()' function. This oversight can cause a NULL pointer dereference, potentially leading to a denial-of-service condition.

Impact

Exploitation of this vulnerability causes a NULL pointer dereference, leading to a denial-of-service condition.
