Detailsinfo

A vulnerability was found in Linux Kernel up to 5.19.16/6.0.2. It has been classified as critical. This affects the function ath11k_mhi_register. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

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.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2022-50418 since 09/17/2025. Technical details of the vulnerability are known, but there is no available exploit.
