CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2024-44984 – bnxt_en: Fix double DMA unmapping for XDP_REDIRECT
https://notcve.org/view.php?id=CVE-2024-44984
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix double DMA unmapping for XDP_REDIRECT Remove the dma_unmap_page_attrs() call in the driver's XDP_REDIRECT code path. This should have been removed when we let the page pool handle the DMA mapping. This bug causes the warning: WARNING: CPU: 7 PID: 59 at drivers/iommu/dma-iommu.c:1198 iommu_dma_unmap_page+0xd5/0x100 CPU: 7 PID: 59 Comm: ksoftirqd/7 Tainted: G W 6.8.0-1010-gcp #11-Ubuntu Hardware name: Dell Inc.
