  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/cxgb4: free STAG index when TPT entry write fails  write_tpt_entry() allocates a new STAG index with c4iw_get_resource() and bumps stats.stag.cur before programming the entry.  When write_adapter_mem() fails, it returns the error without releasing the index or reversing the statistic.  No MR is inserted into rhp-\u003emrs, so deregistration never reclaims it, leaking the index until device teardown.  Record whether this call allocated the index and, on a failed write, return it to tpt_table and decrement stats.stag.cur.  Key the rollback on both the write error and that flag, not the error alone: a non-reset update carries a caller-owned STAG that this call did not allocate and must not free.",
