The buffer is released by the common cleanup path\nthrough mlx5r_umr_unmap_free_xlt().\n\nAfter mlx5_odp_populate_xlt() became fallible, its error path returned\ndirectly and skipped that cleanup. This leaks the XLT DMA mapping and\nbuffer. If the emergency XLT page was used, it also leaves\nxlt_emergency_page_mutex locked.\n\nBreak out of the loop so execution falls through the existing cleanup path.","state":0,"publishedAt":"2026-08-15T05:59:08.694+00:00","modifiedAt":"2026-10-16T19:05:41.026+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/hw/mlx5/umr.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"1efe8c0670d6a6883faa09c9abc746c741f5664a\",\n                            \"lessThan\": \"ffa85a2c197935ace6f1634ad9eb0a44bc615670\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"1efe8c0670d6a6883faa09c9abc746c741f5664a\",\n                            \"lessThan\": \"9619909d4869afe720904c6888a289b9ac3055b8\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"1efe8c0670d6a6883faa09c9abc746c741f5664a\",\n                            \"lessThan\": \"1eae35b37923cb71b0cb5136d00671440d488b9f\",\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/hw/mlx5/umr.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.40\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.1.5\",\n                            \"lessThanOrEqual\": \"7.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/ffa85a2c197935ace6f1634ad9eb0a44bc615670","https://git.kernel.org/stable/c/9619909d4869afe720904c6888a289b9ac3055b8","https://git.kernel.org/stable/c/1eae35b37923cb71b0cb5136d00671440d488b9f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-74396","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-74396","identifiers":["CVE-2026-74396"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
