Regular desktop usage won't\ntrigger this due to the fact that virtual machines will not have\nmultiple GPUs but it enables better test coverage in IGT." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Linux", "product": { "product_data": [ { "product_name": "Linux", "version": { "version_data": [ { "version_affected": "<", "version_name": "65674218b43f", "version_value": "9a9716bbbf3d" }, { "version_affected": "<", "version_name": "b32233acceff", "version_value": "5c12391ee1ab" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "6.9", "status": "affected" }, { "version": "0", "lessThan": "6.9", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.49", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.8", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/9a9716bbbf3dd6b6cbefba3abcc89af8b72631f4", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/9a9716bbbf3dd6b6cbefba3abcc89af8b72631f4" }, { "url": "https://git.kernel.org/stable/c/5c12391ee1ab59cb2f3be3f1f5e6d0fc0c2dc854", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/5c12391ee1ab59cb2f3be3f1f5e6d0fc0c2dc854" }, { "url": "https://git.kernel.org/stable/c/50f1199250912568606b3778dc56646c10cb7b04", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/50f1199250912568606b3778dc56646c10cb7b04" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
