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.
