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