  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix memory leak in parse_lease_state()\n\nThe previous patch that added bounds check for create lease context\nintroduced a memory leak. When the bounds check fails, the function\nreturns NULL without freeing the previously allocated lease_ctx_info\nstructure.\n\nThis patch fixes the issue by adding kfree(lreq) before returning NULL\nin both boundary check cases.",
