We check that len with\n\n\txsk_pool_get_rx_frame_size() + vi->hdr_len\n\nto ensure the provided len does not larger than the allocated chunk\nsize. The additional vi->hdr_len is because in virtnet_add_recvbuf_xsk,\nwe use part of XDP_PACKET_HEADROOM for virtio header and ask the vhost\nto start placing data from\n\n\thard_start + XDP_PACKET_HEADROOM - vi->hdr_len\nnot\n\thard_start + XDP_PACKET_HEADROOM\n\nBut the first buffer has virtio_header, so the maximum frame's length in\nthe first buffer can only be\n\n\txsk_pool_get_rx_frame_size()\nnot\n\txsk_pool_get_rx_frame_size() + vi->hdr_len\n\nlike in the current check.\n\nThis commit adds an additional argument to buf_to_xdp differentiate\nbetween the first buffer and other ones to correctly calculate the maximum\nframe's length."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/virtio_net.c"],"versions":[{"version":"a4e7ba7027012f009f22a68bcfde670f9298d3a4","lessThan":"892f6ed9a4a38bb3360fdff091b9241cfa105b61","status":"affected","versionType":"git"},{"version":"a4e7ba7027012f009f22a68bcfde670f9298d3a4","lessThan":"6013bb6bc24c2cac3f45b37a15b71b232a5b00ff","status":"affected","versionType":"git"},{"version":"a4e7ba7027012f009f22a68bcfde670f9298d3a4","lessThan":"5177373c31318c3c6a190383bfd232e6cf565c36","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/virtio_net.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.12.37","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.6","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.12.37"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.15.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.16"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/892f6ed9a4a38bb3360fdff091b9241cfa105b61"},{"url":"https://git.kernel.org/stable/c/6013bb6bc24c2cac3f45b37a15b71b232a5b00ff"},{"url":"https://git.kernel.org/stable/c/5177373c31318c3c6a190383bfd232e6cf565c36"}],"title":"virtio-net: xsk: rx: fix the frame's length check","x_generator":{"engine":"bippy-1.2.0"}}}}
