  "title": "net: libwx: properly reset Rx ring descriptor",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: libwx: properly reset Rx ring descriptor  When device reset is triggered by feature changes such as toggling Rx VLAN offload, wx-\u003Edo_reset() is called to reinitialize Rx rings. The hardware descriptor ring may retain stale values from previous sessions. And only set the length to 0 in rx_desc[0] would result in building malformed SKBs. Fix it to ensure a clean slate after device reset.  [  549.186435] [     C16] ------------[ cut here ]------------ [  549.186457] [     C16] kernel BUG at net/core/skbuff.c:2814!
