CVE-2025-38072

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A divide error occurs in the libnvdimm driver when a faulty CXL memory device returns a broken zero LSA size in its memory device information. This error happens because the config size is assigned to zero LSA size, which then sets max xfer to zero. A subsequent DIV ROUND UP() causes a division by zero. The issue is resolved by checking the config size parameter.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
