CVE-2025-37840 addresses a warning triggered during power management (PM) resume in the Linux kernel's Broadcom NAND driver. The issue was caused by an uninitialized nand_operation structure leading to a WARN_ON condition. The fix replaces the low-level nand_reset_op() call with the higher-level nand_reset() function during PM resume to comply with the controller's single die NAND chip support.
