  "title": "mtd: spinand: fix NULL pointer dereference with no ECC engine",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  mtd: spinand: fix NULL pointer dereference with no ECC engine  When \u0022nand-no-ecc-engine\u0022 is set in DT, nanddev_get_ecc_engine() takes the NAND_ECC_ENGINE_TYPE_NONE path and returns success while leaving nand-\u003Eecc.engine NULL. The SPI-NAND code nevertheless dereferences it unconditionally to test for a pipelined engine, so probing such a device oopses immediately.  Rather than open-coding the test three times, add a nand_ecc_is_pipelined() helper to the NAND core that folds the NULL check into the integration comparison, and use it everywhere. Future callers then cannot reintroduce the problem.",
