This causes driver initialization to fail on\nApple eMac's with GeForce 2 MX GPUs, leaving the system with no working\nconsole.\n\nThis is probably only seen on OpenFirmware machines like PowerPC Macs\nbecause the BIOS image provided by OF is only the used parts of the ROM,\nnot a power-of-two blocks read from PCI directly so PCs always have\nempty bytes at the end that are never accessed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-193"],"references":["https://git.kernel.org/stable/c/1b777d4d9e383d2744fc9b3a09af6ec1893c8b1a","https://git.kernel.org/stable/c/909d3ec1bf9f0ec534bfc081b77c0836fea7b0e2","https://git.kernel.org/stable/c/acc887ba88333f5fec49631f12d8cc7ebd95781c","https://git.kernel.org/stable/c/b2a21669ee98aafc41c6d42ef15af4dab9e6e882","https://git.kernel.org/stable/c/d4b746e60fd8eaa8016e144223abe91158edcdad"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2022-48732","score":0.00235,"percentile":0.14503,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
