Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to a reservation leak within the btrfs file system when inserting inline extents. Specifically, if allocation of a path or joining a transaction fails during the
cow file range inline() function, reserved qgroup data is not freed, leading to a memory leak. The issue is addressed by ensuring the btrfs qgroup free data() function is called in these error scenarios.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
