The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to an out-of-bounds read in sdw_add_element_group_count when processing SoundWire group rate and lane entries. A local user can trigger the vulnerable code path to cause a denial of service.
The issue occurs because the loop iterates with an index equal to the element count.
