I confirmed v6.1.70 is vulnerable with the poc, v6.1.172 not ok, I am doing
some bisects to figure out which version vulnerable or just fix poc.
FYI,[PATCH net v3] rxrpc: Also unshare DATA/RESPONSE packets when paged frags are present
... Fixes: d0d5c0cd1e71 ("rxrpc: Use skb_unshare() rather than skb_cow_data()")
is in v5.3-rc7...:(, so it will affect 5.10.y 5.15.y 6.1.y than someone says >6.5 ver:(.
