  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: mana: Fix race on per-CQ variable napi work_done  After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be cleared, and another CPU can start napi thread and access per-CQ variable, cq-\u003Ework_done. If the other thread (for example, from busy_poll) sets it to a value \u003E= budget, this thread will continue to run when it should stop, and cause memory corruption and panic.  To fix this issue, save the per-CQ work_done variable in a local variable before napi_complete_done(), so it won\u0027t be corrupted by a possible concurrent thread after napi_complete_done().  Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done variable race is fixed, so the driver is able to reliably support features like busy_poll.",
