CVE-2025-71106

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fs: PM: Fix reverse check in filesystems_freeze_callback()<br /> <br /> The freeze_all_ptr check in filesystems_freeze_callback() introduced by<br /> commit a3f8f8662771 ("power: always freeze efivarfs") is reverse which<br /> quite confusingly causes all file systems to be frozen when<br /> filesystem_freeze_enabled is false.<br /> <br /> On my systems it causes the WARN_ON_ONCE() in __set_task_frozen() to<br /> trigger, most likely due to an attempt to freeze a file system that is<br /> not ready for that.<br /> <br /> Add a logical negation to the check in question to reverse it as<br /> appropriate.
