CVE-2022-50418

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath11k: mhi: fix potential memory leak in ath11k_mhi_register()<br /> <br /> mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets<br /> some error, mhi_ctrl should be freed with mhi_free_controller(). But<br /> when ath11k_mhi_read_addr_from_dt() fails, the function returns without<br /> calling mhi_free_controller(), which will lead to a memory leak.<br /> <br /> We can fix it by calling mhi_free_controller() when<br /> ath11k_mhi_read_addr_from_dt() fails.
