The commit "ath9k: stomp audio profiles on weak signal strength" failed to take care of new stomp type while programming concurrent tx priority. That leads to array index out of bounds access. drivers/net/wireless/ath/ath9k/btcoex.c:414 ath9k_hw_btcoex_set_concur_txprio() error: buffer overflow 'stomp_txprio' 4 <= 4 Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> --- drivers/net/wireless/ath/ath9k/mci.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
