CVE-2024-50001

CVE-2024-50001 affects the Linux kernel, specifically the net/mlx5 multi-packet WQE transmit path. The root cause is an erroneous unmap of a DMA mapping when DMA mapping allocation fails; this can remove a DMA mapping that is still required. If the PCI function subsequently presents the IOVA, the...
