<p><a href="https://www.cve.org/CVERecord?id=CVE-2025-48386">CVE-2025-48386</a> is regarding a vulnerability in Git where the wincred credential helper uses a static buffer (<code>target</code>) as a unique key for storing and comparing against internal storage. This credential helper does not properly bounds check the available space remaining in the buffer before appending to it with <code>wcsncat()</code>, leading to potential buffer overflows. GitHub created this CVE on their behalf. The documented Visual Studio updates incorporate updates in Git which address this vulnerability.</p> <p>Please see <a href="https://www.cve.org/CVERecord?id=CVE-2025-48386">CVE-2025-48386</a> for more information.</p>
