Hi Greg, Sasha, Could you please cherry-pick: 29ad9a305943 ("netfilter: nf_tables: fix underflow in chain reference counter") b8ae60de6fd3 ("netfilter: nf_tables: fix underflow in object reference counter" into 6.1.y? Other -stable kernels I have just audited do not need these updates, since this fix have been already included in my recent -stable backports. Thanks. P.S: Moving forward, I will add the Cc: stable@xxxxxxxxxxxxxxx tag to patches as Greg suggested.
