Vulnerability from github – Published: 2025-10-22 18:30 – Updated: 2025-10-22 18:30

Details

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

dpaa2-eth: retrieve the virtual address before dma_unmap

The TSO header was DMA unmapped before the virtual address was retrieved and then used to free the buffer. This meant that we were actually removing the DMA map and then trying to search for it to help in retrieving the virtual address. This lead to a invalid virtual address being used in the kfree call.

Fix this by calling dpaa2_iova_to_virt() prior to the dma_unmap call.
