In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: mhi: fix potential memory leak in ath11kmhiregister() mhialloccontroller() allocates a memory space for mhictrl. When gets some error, mhictrl should be freed with mhifreecontroller(). But when ath11kmhireadaddrfromdt() fails, the function returns without calling mhifreecontroller(), which will lead to a memory leak. We can fix it by calling mhifreecontroller() when ath11kmhireadaddrfromdt() fails.
