This is incorrect since the\ndpaa2_switch_free_fd() is intended to be used on Tx frame descriptors,\nmeaning that it expects in the software annotation area of the FD data\nto find a valid skb pointer on which to call dev_kfree_skb().\n\nFix this by extracting the dma_unmap_page() from\ndpaa2_switch_build_linear_skb() directly into the dpaa2_switch_rx()\nfunction. This allows us to directly use free_pages() in case of an\nerror before an SKB was created and kfree_skb() afterwards.\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 791068c962469af0090e1a1ee63657fb9eef40db`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < ee54f8d7e642c44cfcc2dcb390b4c50e145d81b8`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 259ad6093204b999d41e7e6d0ad90ef9a71a44ab`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < f4ceb8e3d6d5becb4cda7a7098a8638e18c835a1`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < fa232b4496cb59503ae5108c756cbe10e59b0bc3`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 74c1c9f5c0c30bbd0c2cf87b6e3507e7ea46c13d`\n- `Linux < 5.15.222`\n- `Linux < 6.1.189`\n- `Linux < 6.6.158`\n- `Linux < 6.12.111`\n- `Linux < 6.18.53`\n- `Linux (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
