If the response\nslot remains in use after the timeout and after the polled CREQ service\nattempt, the loop starts another full timeout period and can repeat\nforever.\n\nReturn -ENODEV after a timed out wait that still has no response.  The\nexisting caller then marks FIRMWARE_STALL_DETECTED and returns\n-ETIMEDOUT to the command issuer.","state":0,"publishedAt":"2026-09-17T16:11:49.443+00:00","modifiedAt":"2026-10-19T09:06:25.393+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/bng_re/bng_fw.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"53c6ee7d7f68a0679f8ddc703338aa2550d24a17\",\n                            \"lessThan\": \"02d4ee65dc2e883f554169155937742e6014c243\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"53c6ee7d7f68a0679f8ddc703338aa2550d24a17\",\n                            \"lessThan\": \"5f9576c6734abca88a02db72c466e09d2eddf160\",\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/bng_re/bng_fw.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\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/02d4ee65dc2e883f554169155937742e6014c243","https://git.kernel.org/stable/c/5f9576c6734abca88a02db72c466e09d2eddf160"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93153","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93153","identifiers":["CVE-2026-93153"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
