| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a write hole while writing out freeing tree nodes of a tree-log tree in the btrfs component of the Linux kernel. This occurs because the current code fails to re-dirty a node when the tree-log tree's depth is greater or equal to 2, leading to a transaction abort with an error. The problem is specific to zoned btrfs, where a freed tree node needs to be re-dirtied to ensure btrfs can write the region without leaving a hole on a zoned device.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
