5.5 · MEDIUMOverview
CVE-2025-71106 is a medium-severity vulnerability affecting linux linux_kernel. It was published on January 14, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
fs: PM: Fix reverse check in filesystems_freeze_callback()
The freeze_all_ptr check in filesystems_freeze_callback() introduced by
commit a3f8f8662771 ("power: always freeze efivarfs") is reverse which
quite confusingly causes all file systems to be frozen when
filesystem_freeze_enabled is false.
On my systems it causes the WARN_ON_ONCE() in __set_task_frozen() to
trigger, most likely due to an attempt to freeze a file system that is
not ready for that.
Add a logical negation to the check in question to reverse it as
appropriate.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
