No client can have registered a dmb at that point, so\nno dmb interrupt can occur, but a GID event interrupt can, and\nism_handle_irq() takes dibs->lock unconditionally on entry, before it\ninspects anything else.\n\nInitialise the lock in dibs_dev_alloc() instead, so that it is valid as\nsoon as a driver can publish the device to its interrupt handler.","state":0,"publishedAt":"2026-08-22T15:32:02.049+00:00","modifiedAt":"2026-10-16T19:06:02.395+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/dibs/dibs_main.c\",\n                        \"include/linux/dibs.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"cc21191b584c6f7836b0f10774f8278b7cbfba10\",\n                            \"lessThan\": \"fe79571f40434b257d68cbfb7b3ae93a794d8a11\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"cc21191b584c6f7836b0f10774f8278b7cbfba10\",\n                            \"lessThan\": \"2926031acba100d0c18fcfaa7a2ed29609318848\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"cc21191b584c6f7836b0f10774f8278b7cbfba10\",\n                            \"lessThan\": \"c27e360545373b7aee9862a5beef3b9fb3df0c25\",\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/dibs/dibs_main.c\",\n                        \"include/linux/dibs.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.18\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.18\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.45\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.1.9\",\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:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://git.kernel.org/stable/c/fe79571f40434b257d68cbfb7b3ae93a794d8a11","https://git.kernel.org/stable/c/2926031acba100d0c18fcfaa7a2ed29609318848","https://git.kernel.org/stable/c/c27e360545373b7aee9862a5beef3b9fb3df0c25"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-74617","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-74617","identifiers":["CVE-2026-74617"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
