CVE-2024-27008 is an out-of-bounds array-access vulnerability in the Linux kernel DRM Nouveau NV04 driver. In fabricate_dcb_output(), the Output Resource value is used with ffs() as an index into the dac_users array. When the dcb->or value is zero, this produces an invalid index and can access the array out of bounds. The fix treats the function's or argument as a bit number to set rather than a bitmask value and replaces hard-coded values with the appropriate nouveau_or enumeration macros.
