Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been identified, specifically in the dpaa2-eth component. The issue arises when the TSO header is DMA unmapped before retrieving the virtual address, leading to an invalid virtual address being used in the kfree call. This results in a kernel paging request error. The vulnerability is resolved by calling dpaa2 iova to virt() prior to the dma unmap call.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
