Hi Greg, Sasha, Thadeu, Today there was mentioning of https://www.jmpeax.dev/The-tale-of-a-GSM-Kernel-LPE.html a LPE from the n_gsm module. I do realize, Thadeu mentioned the possible attack surface already back in https://lore.kernel.org/all/ZMuRoDbMcQrsCs3m@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx/#t Published exploits are referenced as well through the potential initial finder in https://github.com/YuriiCrimson/ExploitGSM . While 67c37756898a ("tty: n_gsm: require CAP_NET_ADMIN to attach N_GSM0710 ldisc") is not the fix itself, it helps mitigating against this issue. Thus can you consider applying this still to the stable series as needed? I think it should go at least back to 5.15.y but if Iunderstood Thadeu correctly then even further back to the still supported stable branches. What do you think? Regards, Salvatore
