Description OSIDB Bzimport 2026-05-06 13:10:20 UTC
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.
