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

wifi: ath11k: fix NULL dereference in ath11k_qmi_m3_load()

If ab->fw.m3_data points to data, then fw pointer remains null.
Further, if m3_mem is not allocated, then fw is dereferenced to be
passed to ath11k_err function.

Replace fw->size by m3_len.
