It suggest a maximum number of\n32 connectors. But the way it's used is like MAX_DISPLAY_COUNT.\nHence we're off by one with DRM core, which supports a max of 32\nconnectors.\n\nRename AMDGPU_DM_MAX_DISPLAY_INDEX to AMDGPU_DM_MAX_DISPLAY_COUNT\nto match its actual use, and increase the size to 32 to match the\noriginally intended size.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0fa116a17b69a28712cdf209318e345b676d7f6c","tags":[]},{"url":"https://git.kernel.org/stable/c/261e0fe4e2c99f687114b64b10b98db964b475f4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
