Description
A flaw was found in the Linux kernel's ec_bhf ethernet driver. An issue in the error handling path of the dma_free_coherent() function incorrectly uses priv->rx_buf.alloc_len as the Direct Memory Access (DMA) handle instead of priv->rx_buf.alloc_phys. This improper unmapping of the buffer could lead to memory corruption or system instability, potentially resulting in a Denial of Service (DoS).
