Severity CVSS v4.0:
Pending analysis

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ext4: regenerate buddy after block freeing failed if under fc replay<br /> <br /> This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant<br /> mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on<br /> code in mb_free_blocks(), fast commit replay can end up marking as free<br /> blocks that are already marked as such. This causes corruption of the<br /> buddy bitmap so we need to regenerate it in that case.
