HighCVSS 8.8/10Last modified Nov 11, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: ec_bhf: Fix dma_free_coherent() dma handle

dma_free_coherent() in error path takes priv->rx_buf.alloc_len as the dma handle. This would lead to improper unmapping of the buffer.

Change the dma handle to priv->rx_buf.alloc_phys.
