However\nrpcrdma_ep_create() currently stores that pointer in ep->re_id only\nafter rpcrdma_create_id() returns.\n\nA local administrator can race an NFS/RDMA mount against RDMA device\nremoval. If rpcrdma_remove_one() observes the just-registered\nnotification before rpcrdma_ep_create() assigns ep->re_id,\nrpcrdma_ep_removal_done() calls trace_xprtrdma_device_removal(NULL).\nThe tracepoint dereferences id->device->name and copies\nid->route.addr.dst_addr, so the callback can crash the kernel with a\nNULL pointer dereference.\n\nStore the rdma_cm_id in ep->re_id immediately before publishing\nep->re_rn. The existing error path still destroys the id directly if\nregistration fails; ep is then freed by the caller without using\nep->re_id. Remove the later duplicate assignment in rpcrdma_ep_create()."}],"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":"3f4eb9ff923413cdb4c7e171c06d3564f6286712","lessThan":"51248d877bbc6e604e38aeaf776c2781cb4f0dbd","status":"affected","versionType":"git"},{"version":"3f4eb9ff923413cdb4c7e171c06d3564f6286712","lessThan":"28743571c17b58c21a7216fc9faaf8028df5869b","status":"affected","versionType":"git"},{"version":"3f4eb9ff923413cdb4c7e171c06d3564f6286712","lessThan":"264ccd7871915749bee55fe0c39467a7f08d5479","status":"affected","versionType":"git"},{"version":"3f4eb9ff923413cdb4c7e171c06d3564f6286712","lessThan":"bb7caa63e1db22fd03e8dc591b12169e99169dff","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":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","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":"6.11","versionEndExcluding":"6.12.97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/51248d877bbc6e604e38aeaf776c2781cb4f0dbd"},{"url":"https://git.kernel.org/stable/c/28743571c17b58c21a7216fc9faaf8028df5869b"},{"url":"https://git.kernel.org/stable/c/264ccd7871915749bee55fe0c39467a7f08d5479"},{"url":"https://git.kernel.org/stable/c/bb7caa63e1db22fd03e8dc591b12169e99169dff"}],"title":"xprtrdma: Initialize re_id before removal registration","x_generator":{"engine":"bippy-1.2.0"}}}}
