Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.3.0-next-20230505-00006-g5107a9c821af
Description
The Linux kernel contains an issue within the quota handling mechanism. A warning can occur in the
dqgrab() function during fault injection scenarios involving concurrent quota operations from multiple processes. This can happen when a process attempts to acquire a quota while another process is suspending or resuming quota operations. The issue arises because the DQ ACTIVE B flag may not be set on the dquot structure when dqgrab() is called. This can lead to a warning being triggered during quota management.Recommendations
Update to version 6.3.0-next-20230505-00006-g5107a9c821af or a later version to resolve this issue.
