CVE-2026-80851

CVE-2026-80851 is a race condition in the Linux kernel's GTP (GPRS Tunnelling Protocol) module . PDP contexts could be double-deleted when the generic-netlink delete path (GTP_CMD_DELPDP) and GTP device unregistration (RTM_DELLINK) ran concurrently, since the former holds only RCU while the latte...
