Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the NTFS driver due to a lack of serialization when accessing volume labels. This occurs when the
FS IOC SETFSLABEL operation replaces the vol->volume label while the FS IOC GETTSLABEL operation reads it concurrently. A use-after-free is a condition where a program continues to use a pointer after the memory it points to has been freed, which can lead to system instability or crashes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
