  "description": "In the Linux kernel, the following vulnerability has been resolved:  net/mlx5e: Fix crash caused by calling __xfrm_state_delete() twice  The km.state is not checked in driver\u0027s delayed work. When xfrm_state_check_expire() is called, the state can be reset to XFRM_STATE_EXPIRED, even if it is XFRM_STATE_DEAD already. This happens when xfrm state is deleted, but not freed yet. As __xfrm_state_delete() is called again in xfrm timer, the following crash occurs.  To fix this issue, skip xfrm_state_check_expire() if km.state is not XFRM_STATE_VALID.
