If the condition changes between these two tests, the MSR and irq\nsoft-mask state will become corrupted, leading to warnings and possible\ncrashes. For example, if the branch is initially true then false,\nMSR[EE] will be 0 but PACA_IRQ_HARD_DIS clear and EE may not get\nenabled, leading to warnings in irq_64.c." } ] }, "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": "13799748b957", "version_value": "86f7e4239336" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "5.14", "status": "affected" }, { "version": "0", "lessThan": "5.14", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.94", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.12", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.2", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/86f7e423933608d536015a0f2eb9e0338c1227e0", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/86f7e423933608d536015a0f2eb9e0338c1227e0" }, { "url": "https://git.kernel.org/stable/c/6f097c24815e67909a1fcc2c605586d02babd673", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/6f097c24815e67909a1fcc2c605586d02babd673" }, { "url": "https://git.kernel.org/stable/c/2ea31e2e62bbc4d11c411eeb36f1b02841dbcab1", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/2ea31e2e62bbc4d11c411eeb36f1b02841dbcab1" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
