In commit42bf50a179("can: isotp: support MSG_TRUNC flag when reading from socket") a new check for recvmsg flags has been introduced that only checked for the flags that are handled in isotp_recvmsg() itself. This accidentally removed the MSG_PEEK feature flag which is processed later in the call chain in __skb_try_recv_from_queue(). Add MSG_PEEK to the set of valid flags to restore the feature.
