  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: spinand: fix NULL pointer dereference with no ECC engine\n\nWhen \"nand-no-ecc-engine\" is set in DT, nanddev_get_ecc_engine() takes\nthe NAND_ECC_ENGINE_TYPE_NONE path and returns success while leaving\nnand-\u003eecc.engine NULL. The SPI-NAND code nevertheless dereferences it\nunconditionally to test for a pipelined engine, so probing such a\ndevice oopses immediately.\n\nRather than open-coding the test three times, add a\nnand_ecc_is_pipelined() helper to the NAND core that folds the NULL\ncheck into the integration comparison, and use it everywhere. Future\ncallers then cannot reintroduce the problem.",
