CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:HIn the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix dma_free_coherent() pointer dma_alloc_coherent() allocates a DMA mapped buffer and stores the addresses in XXX_unaligned fields. Those should be reused when freeing the buffer rather than the aligned addresses. A flaw was found in the Linux kernel's ath12k wifi driver. A local attacker could exploit this vulnerability by triggering the device driver teardown path. The driver incorrectly passes aligned memory addresses to dma_free_coherent() instead of the original unaligned addresses during cleanup. This improper memory deallocation can lead to memory leaks, data corruption, or kernel crashes, ultimately resulting in a denial of service.
