CVE-2025-38206

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: A double free issue in the exfat module has been resolved. The double free could occur in a specific path involving the exfat create upcase table(), exfat free upcase table(), exfat load default upcase table(), and exfat kill sb() functions. This issue is related to the delayed free() function, which calls exfat free upcase table() and results in a double free of the ->vol utbl variable. The patch sets ->vol util to NULL after freeing it to prevent this issue.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
