Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition exists within the Btrfs file system related to quota management. Specifically, the issue occurs when enabling quotas, where a transaction commit is followed by setting the quota root and flags. If the qgroup rescan worker initialization fails, the quota root may be freed while
fs info->quota root still points to it, potentially leading to a use-after-free condition. The issue arises when an -EINPROGRESS error is encountered during quota enabling, which can occur if the quota rescan ioctl has already been called.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
