The init_conns() and stop-and-destroy paths then call\ndestroy_con_cq_qp() while cq is still NULL (no PUT) and only afterwards\nrdma_destroy_id().\n\nCMA serializes the handler against rdma_destroy_id() with handler_mutex,\nbut that does not order the GET against destroy_con_cq_qp(). If\nADDR_RESOLVED has already passed the DESTROYING check, it can take\ncon_mutex, GET credits, and then lose the con to kfree. Device\nunregister later hits WARN_ON(cq->cqe_used) in ib_cq_pool_cleanup().\n\nSet a per-connection flag under con_mutex before CQ/QP teardown so a\nracing ADDR_RESOLVED cannot borrow credits after teardown has begun."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/infiniband/ulp/rtrs/rtrs-clt.c","drivers/infiniband/ulp/rtrs/rtrs-clt.h"],"versions":[{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"a82cca40139d9fcae8208901856bd5bb4051f097","status":"affected","versionType":"git"},{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"74c4ed55e61f1b65ddbebc5b635d136461a1c3da","status":"affected","versionType":"git"},{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"6f8020fe7465f49e234a576c04e415e9d08c7878","status":"affected","versionType":"git"},{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"31024e158b45358370a0a14ed96589e6aa62d6cb","status":"affected","versionType":"git"},{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"8f253d5893f991742464b9e7203c43fc08d0aa11","status":"affected","versionType":"git"},{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"bf88ac4867050112a6c819c8d1a7209bf48ef427","status":"affected","versionType":"git"},{"version":"3b89e92c2a95a39c38a3808f4528e502a39bd94d","lessThan":"2ae16aaa78b5edc6e6d0904c84fd9cdfb762bcda","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/infiniband/ulp/rtrs/rtrs-clt.c","drivers/infiniband/ulp/rtrs/rtrs-clt.h"],"versions":[{"version":"5.13","status":"affected"},{"version":"0","lessThan":"5.13","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc4","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":"5.13","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.13","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.13","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.13","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.13","versionEndExcluding":"6.18.54"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.13","versionEndExcluding":"7.2.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.13","versionEndExcluding":"7.3-rc4"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a82cca40139d9fcae8208901856bd5bb4051f097"},{"url":"https://git.kernel.org/stable/c/74c4ed55e61f1b65ddbebc5b635d136461a1c3da"},{"url":"https://git.kernel.org/stable/c/6f8020fe7465f49e234a576c04e415e9d08c7878"},{"url":"https://git.kernel.org/stable/c/31024e158b45358370a0a14ed96589e6aa62d6cb"},{"url":"https://git.kernel.org/stable/c/8f253d5893f991742464b9e7203c43fc08d0aa11"},{"url":"https://git.kernel.org/stable/c/bf88ac4867050112a6c819c8d1a7209bf48ef427"},{"url":"https://git.kernel.org/stable/c/2ae16aaa78b5edc6e6d0904c84fd9cdfb762bcda"}],"title":"RDMA/rtrs-clt: Fix CQ pool leak when connect is interrupted","x_generator":{"engine":"bippy-1.2.0"}}}}
