Entries for the\nRNDIS header and the skb linear data come from kmalloc'd memory and\nare always in the kernel direct map, but entries for skb fragments\nreference page cache or user pages, which on 32-bit x86 with\nCONFIG_HIGHMEM=y can live above the LOWMEM boundary. For such a page\nphys_to_virt() returns an address outside the direct map and the\nsubsequent memcpy() faults on the transmit softirq path, which is\nfatal.\n\nMap the pages with kmap_local_page() instead, handling two properties\nof the page buffer entries:\n\n - pb[i].pfn is a Hyper-V PFN at HV_HYP_PAGE_SIZE (4K) granularity,\n not a native PFN. Reconstruct the physical address first and derive\n the native page from it, so the mapping stays correct where\n PAGE_SIZE > HV_HYP_PAGE_SIZE (e.g. arm64 with 64K pages).\n\n - Since commit 41a6328b2c55 (\"hv_netvsc: Preserve contiguous PFN\n grouping in the page buffer array\"), an entry describes a full\n physically contiguous fragment and pb[i].len can exceed PAGE_SIZE,\n while kmap_local_page() maps a single page. Copy page by page,\n splitting at native page boundaries.\n\nThe copy path only handles packets smaller than the send section size\n(6144 bytes by default); larger packets take the cp_partial path where\nonly the RNDIS header is copied. So entries here are bounded by the\nsection size and a copy is split at most once on 4K-page systems. On\n!CONFIG_HIGHMEM configs kmap_local_page() folds to page_address() and\nno mapping work is added.", "category":"general", "title":"Synopsis" } ], "publisher":null, "references":[ { "summary":"nvd

"text":"In the Linux kernel, the following vulnerability has been resolved:\n\nhv_netvsc: use kmap_local_page in netvsc_copy_to_send_buf\n\nnetvsc_copy_to_send_buf() copies page buffer entries into the VMBus\nsend buffer using phys_to_virt() on the entry PFN. Entries for the\nRNDIS header and the skb linear data come from kmalloc'd memory and\nare always in the kernel direct map, but entries for skb fragments\nreference page cache or user pages, which on 32-bit x86 with\nCONFIG_HIGHMEM=y can live above the LOWMEM boundary. For such a page\nphys_to_virt() returns an address outside the direct map and the\nsubsequent memcpy() faults on the transmit softirq path, which is\nfatal.\n\nMap the pages with kmap_local_page() instead, handling two properties\nof the page buffer entries:\n\n - pb[i].pfn is a Hyper-V PFN at HV_HYP_PAGE_SIZE (4K) granularity,\n not a native PFN. Reconstruct the physical address first and derive\n the native page from it, so the mapping stays correct where\n PAGE_SIZE > HV_HYP_PAGE_SIZE (e.g. arm64 with 64K pages).\n\n - Since commit 41a6328b2c55 (\"hv_netvsc: Preserve contiguous PFN\n grouping in the page buffer array\"), an entry describes a full\n physically contiguous fragment and pb[i].len can exceed PAGE_SIZE,\n while kmap_local_page() maps a single page. Copy page by page,\n splitting at native page boundaries.\n\nThe copy path only handles packets smaller than the send section size\n(6144 bytes by default); larger packets take the cp_partial path where\nonly the RNDIS header is copied. So entries here are bounded by the\nsection size and a copy is split at most once on 4K-page systems. On\n!CONFIG_HIGHMEM configs kmap_local_page() folds to page_address() and\nno mapping work is added.", "category":"description", "title":"Vulnerability Description" } ], "product_status":{ "fixed":[
