Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ksmbd: fix buffer validation by including null terminator size in EA length<br />
<br />
The smb2_set_ea function, which handles Extended Attributes (EA),<br />
was performing buffer validation checks that incorrectly omitted the size<br />
of the null terminating character (+1 byte) for EA Name.<br />
This patch fixes the issue by explicitly adding &#39;+ 1&#39; to EaNameLength where<br />
the null terminator is expected to be present in the buffer, ensuring<br />
the validation accurately reflects the total required buffer size.
