CVE-2025-37931

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the btrfs file system. The issue occurs when running machines with a 64k page size and a 16k nodesize, causing tree log corruption due to not writing out dirty blocks sometimes. This affects all metadata writes. The problem arises from the subpage bitmap being based on the number of sectors that an EB has, leading to incorrect addressing and potentially skipping the writeout of dirty extent buffers.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
