What to do
AI-suggested
A fix is available and has been applied in the Linux kernel to replace nand_reset_op() with nand_reset() during PM resume. Users should update to the fixed kernel version once released to eliminate the warning and potential instability. No additional mitigation is required beyond applying the official fix.
Description
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.
