CVE-2025-22038

HighCVSS 7.1/10Last modified Jul 30, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: validate zero num_subauth before sub_auth is accessed

Access psid->sub_auth[psid->num_subauth - 1] without checking if num_subauth is non-zero leads to an out-of-bounds read. This patch adds a validation step to ensure num_subauth != 0 before sub_auth is accessed.
