However, the allocated\nresource was not given a name, which causes the kernel resource tree\nto contain an entry marked as \"<BAD>\" under /proc/iomem on x86\nplatforms.\n\nDuring boot, this unnamed resource can lead to a critical hang because\nsubsequent resource lookups and conflict checks fail to handle the\ninvalid entry properly.\n\n## Affected\n\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < 1d56025a3af50db0f3da2792f41eb9943eee5324`\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < c7b986adc9e9336066350542ac5a2005d305ae78`\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < 47c910965c936724070d2a8094a4c3ed8f452856`\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < d2c7c90aca7b37f60f16b2bedcfeb16204f2f35d`\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < f7b6370d0fbee06a867037d675797a606cb62e57`\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < c6a2dd4f2e4e6cbdfe7a1618160281af897b75db`\n- `Linux >= dc3c56b703dad4aec8a9b3dd86f03a90d0c26a2d < 7aa31ee9ec92915926e74731378c009c9cc04928`\n- `Linux 3.3`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
