Description OSIDB Bzimport 2025-12-24 12:04:51 UTC
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
