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.","state":0,"publishedAt":"2026-10-06T08:46:42.583+00:00","modifiedAt":"2026-10-19T09:18:05.923+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/infiniband/ulp/rtrs/rtrs-clt-trace.h\",\n                        \"drivers/infiniband/ulp/rtrs/rtrs-srv-trace.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5a93929d9f9a1d82946ddd49e260b6dd1756ad6d\",\n                            \"lessThan\": \"f79cf42ff23f9120246cd6740eaa26f59c632a4a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"5a93929d9f9a1d82946ddd49e260b6dd1756ad6d\",\n                            \"lessThan\": \"99c24a8968ebef0573825b5cb89d5985d51635b9\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/infiniband/ulp/rtrs/rtrs-clt-trace.h\",\n                        \"drivers/infiniband/ulp/rtrs/rtrs-srv-trace.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.8\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/f79cf42ff23f9120246cd6740eaa26f59c632a4a","https://git.kernel.org/stable/c/99c24a8968ebef0573825b5cb89d5985d51635b9"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98355","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98355","identifiers":["CVE-2026-98355"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
