  "title": "net: rds: clear i_sends on setup unwind",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: rds: clear i_sends on setup unwind  The RDS IB connection teardown path is written so it can run during partial startup and on repeated shutdown attempts. It uses NULL pointers to distinguish resources that are still owned from resources that have already been released.  When rds_ib_setup_qp() fails after allocating i_sends but before allocating i_recvs, the sends_out path frees i_sends without clearing the pointer. A later shutdown pass can still treat that stale pointer as a live send ring allocation.  Clear i_sends after vfree() in the error unwind path so the existing shutdown logic continues to use the correct ownership state.",
