If\na reset (nvme reset or IO timeout) occurs before these commands finish,\nreconnect routine may fail to update nvme regs due to insufficient tags,\nwhich will cause kernel hang forever. In order to workaround this issue,\nmaybe we can let reg_read32()/reg_read64()/reg_write32() use reserved\ntags. This maybe safe for nvmf:\n\n1. For the disable ctrl path,  we will not issue connect command\n2. For the enable ctrl / fw activate path, since connect and reg_xx()\n   are called serially.\n\nSo the reserved tags may still be enough while reg_xx() use reserved tags.","state":0,"publishedAt":"2024-07-29T15:04:19.372+00:00","modifiedAt":"2026-10-30T12:18:48.552+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/nvme/host/fabrics.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"e7832cb48a654cd12b2bc9181b2f0ad49d526ac6\",\n                            \"lessThan\": \"2f07bdd363e95b71959d1ea1a7bca53c9e1f1efb\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"e7832cb48a654cd12b2bc9181b2f0ad49d526ac6\",\n                            \"lessThan\": \"cc91c461cf3902993364ea85d8814ba7786c95b1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"e7832cb48a654cd12b2bc9181b2f0ad49d526ac6\",\n                            \"lessThan\": \"165da9c67a26f08c9b956c15d701da7690f45bcb\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"e7832cb48a654cd12b2bc9181b2f0ad49d526ac6\",\n                            \"lessThan\": \"7dc3bfcb4c9cc58970fff6aaa48172cb224d85aa\",\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/nvme/host/fabrics.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"5.4\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.1.191\",\n                            \"lessThanOrEqual\": \"6.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.6.158\",\n                            \"lessThanOrEqual\": \"6.6.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.9.11\",\n                            \"lessThanOrEqual\": \"6.9.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.10\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/2f07bdd363e95b71959d1ea1a7bca53c9e1f1efb","https://git.kernel.org/stable/c/cc91c461cf3902993364ea85d8814ba7786c95b1","https://git.kernel.org/stable/c/165da9c67a26f08c9b956c15d701da7690f45bcb","https://git.kernel.org/stable/c/7dc3bfcb4c9cc58970fff6aaa48172cb224d85aa"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-41082","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-41082","identifiers":["CVE-2024-41082"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
