  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: mchp23k256: use SPI match data for chip caps\n\nThe driver stores chip capacity information in both the OF match table\nand the SPI id table. Probe currently uses of_device_get_match_data(),\nso a non-OF SPI modalias match falls back to mchp23k256_caps even when\nthe SPI id table selected a different part.\n\nUse spi_get_device_match_data() so SPI id-table driver_data is consumed\nwhen OF match data is absent. This keeps the existing default fallback\nwhile avoiding the wrong MTD geometry for id-table-only matches.",
