--- Comment #1 from Alex Guo <[email protected]> --- Additionally, later in `mdb_rebalance`, the code calls: ```c rc = mdb_page_merge(&mn, mc); … rc = mdb_page_merge(mc, &mn); ``` Inside `mdb_page_merge`, `mc_top` is similarly decremented and then used to index `mc_pg` without any preceding check. This same underflow risk exists there and should be guarded with this patch. -- You are receiving this mail because: You are on the CC list for the issue.
