However, this can lead to calling the\nevent tracing code with `clt_path->kobj->name` being `NULL` and thus\ncausing a null pointer dereference when trying to copy from it.\n\nThis just adds a guard to check that the name is not `NULL` before\ncopying from it. The server appears to have a similar pattern."}],"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-trace.h","drivers/infiniband/ulp/rtrs/rtrs-srv-trace.h"],"versions":[{"version":"5a93929d9f9a1d82946ddd49e260b6dd1756ad6d","lessThan":"f79cf42ff23f9120246cd6740eaa26f59c632a4a","status":"affected","versionType":"git"},{"version":"5a93929d9f9a1d82946ddd49e260b6dd1756ad6d","lessThan":"99c24a8968ebef0573825b5cb89d5985d51635b9","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-trace.h","drivers/infiniband/ulp/rtrs/rtrs-srv-trace.h"],"versions":[{"version":"6.1","status":"affected"},{"version":"0","lessThan":"6.1","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":"6.1","versionEndExcluding":"7.2.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"7.3-rc4"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f79cf42ff23f9120246cd6740eaa26f59c632a4a"},{"url":"https://git.kernel.org/stable/c/99c24a8968ebef0573825b5cb89d5985d51635b9"}],"title":"RDMA/rtrs: guard against null kobj name","x_generator":{"engine":"bippy-1.2.0"}}}}
