Lack of data validation - Type confusion In kernel
Description
A logic error was found in the Linux kernel's power management filesystem freeze callback. The freeze_all_ptr check in filesystems_freeze_callback() has reversed logic, causing all filesystems to be frozen when filesystem_freeze_enabled is false (the opposite of intended behavior). This triggers WARN_ON_ONCE() in __set_task_frozen() when attempting to freeze filesystems that are not prepared for freezing.
Mitigation
Update Impact
