Its\nfailure paths return a negative errno and leave ep->re_write_pad_mr set\nto NULL.\n\nrpcrdma_xprt_connect() currently ignores that return value. If\nfrwr_wp_create() fails after the rest of the connection setup succeeds,\nxprt_rdma_connect_worker() treats the connection attempt as successful\nand sets XPRT_CONNECTED. A later NFS/RDMA read with a non-4-byte-aligned\nreceive page length reaches rpcrdma_encode_write_list(), passes the NULL\nwrite-pad MR to encode_rdma_segment(), and dereferences it.\n\nThis is locally triggerable on an NFS/RDMA client after a connect or\nreconnect hits a local MR allocation, DMA-map, MR-map, or post-send\nfailure; a remote peer alone cannot force the local MR setup failure.\n\nCheck the return value and fail the connect as -ENOTCONN, matching the\nadjacent setup failures. This keeps XPRT_CONNECTED clear and lets the\nnormal reconnect path retry."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/sunrpc/xprtrdma/verbs.c"],"versions":[{"version":"21037b8c2258ec40de3b31be9ced43ceb3b784f7","lessThan":"3b252fe1778b2cdd68283146455929801bc2abd7","status":"affected","versionType":"git"},{"version":"21037b8c2258ec40de3b31be9ced43ceb3b784f7","lessThan":"dd798b76a3481e392820c3ae86ed4592858c6b0f","status":"affected","versionType":"git"},{"version":"21037b8c2258ec40de3b31be9ced43ceb3b784f7","lessThan":"6b7be4f3feae322f1c2c40a3bdc99db93574a49e","status":"affected","versionType":"git"},{"version":"21037b8c2258ec40de3b31be9ced43ceb3b784f7","lessThan":"7471e66373a4444a57ef2192f8c4081202c54f45","status":"affected","versionType":"git"},{"version":"21037b8c2258ec40de3b31be9ced43ceb3b784f7","lessThan":"ef3b79edf14b6bfb0d21a26ccb0463f9cf82c6a9","status":"affected","versionType":"git"},{"version":"21037b8c2258ec40de3b31be9ced43ceb3b784f7","lessThan":"0f13fc7c7d2e0427517e63c739277a4cd338b0c5","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/sunrpc/xprtrdma/verbs.c"],"versions":[{"version":"5.16","status":"affected"},{"version":"0","lessThan":"5.16","status":"unaffected","versionType":"semver"},{"version":"6.1.178","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.145","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.97","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"5.16","versionEndExcluding":"6.1.178"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.6.145"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.12.97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3b252fe1778b2cdd68283146455929801bc2abd7"},{"url":"https://git.kernel.org/stable/c/dd798b76a3481e392820c3ae86ed4592858c6b0f"},{"url":"https://git.kernel.org/stable/c/6b7be4f3feae322f1c2c40a3bdc99db93574a49e"},{"url":"https://git.kernel.org/stable/c/7471e66373a4444a57ef2192f8c4081202c54f45"},{"url":"https://git.kernel.org/stable/c/ef3b79edf14b6bfb0d21a26ccb0463f9cf82c6a9"},{"url":"https://git.kernel.org/stable/c/0f13fc7c7d2e0427517e63c739277a4cd338b0c5"}],"title":"xprtrdma: Check frwr_wp_create() during connect","x_generator":{"engine":"bippy-1.2.0"}}}}
