Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ksmbd: fix memory leak in parse_lease_state()<br />
<br />
The previous patch that added bounds check for create lease context<br />
introduced a memory leak. When the bounds check fails, the function<br />
returns NULL without freeing the previously allocated lease_ctx_info<br />
structure.<br />
<br />
This patch fixes the issue by adding kfree(lreq) before returning NULL<br />
in both boundary check cases.
