CVE-2025-37839

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue concerns the Linux kernel, specifically the jbd2 component. It involves a wrong check for journal emptiness, which is not determined by sb->s sequence == 0 but rather by sb->s start == 0. The check can spuriously trigger because 0 is a valid transaction ID. The resolution involves removing the invalid WARN ON.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
