CVE-2025-37962

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 memory leak issue has been identified in the Linux kernel, specifically in the parse lease state() function of the ksmbd module. The problem arose from a previous patch that added bounds checking for create lease context, which introduced a memory leak when the bounds check failed. The function would return NULL without freeing the previously allocated lease ctx info structure. This issue has been resolved by adding a kfree(lreq) call before returning NULL in both boundary check cases.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
