CVE-2023-54016 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix memory leak in rx_desc and tx_desc Currently when ath12k_dp_cc_desc_init() is called we allocate memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during descriptor cleanup rx_descs and tx_descs memory is not freed. This is cause of memory leak. EPSS estimates a 0.16% chance of exploitation in the next 30 days.

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix memory leak in rx_desc and tx_desc Currently when ath12k_dp_cc_desc_init() is called we allocate memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during descriptor cleanup rx_descs and tx_descs memory is not freed. This is cause of memory leak. These allocated memory should be freed in ath12k_dp_cc_cleanup. In ath12k_dp_cc_desc_init(), we can save base address of rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and tx_descs memory using their base address. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
