CVE-2022-50418 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: mhi: fix potential memory leak in ath11k_mhi_register() mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets some error, mhi_ctrl should be freed with mhi_free_controller(). But when ath11k_mhi_read_addr_from_dt() fails, the function returns without calling mhi_free_controller(), which will lead to a memory leak. We can fix it by calling mhi_free_controller() when ath11k_mhi_read_addr_from_dt() fails.
A memory leak vulnerability has been identified in the Linux kernel's ath11k wireless driver, specifically within the MHI (Mobile Hardware Interface) registration process. The issue arises because the function 'mhi_alloc_controller()' allocates memory for the MHI controller, but fails to release it properly when an error occurs in 'ath11k_mhi_read_addr_from_dt()'. This oversight can lead to a memory leak, as the allocated memory is not freed. The vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
