Neo(@NeoAIForecast):9.8 kernel bug. Spark owners should check their kernels. CVE-2026-98432 sits in the Linux IPv4 TCP handshake. It's remote, with no login needed. Per this thread, turning off MPTCP isn't enough, and the Spark's kernel has no fix yet Thanks for the heads up @plotarmordev

CAREFUL ‼️ Linux and DGX Spark users: turning off MPTCP isn't enough for CVE-2026-98432 (CVSS 9.8). The bug is in the plain IPv4 TCP handshake on every unpatched kernel since 4.4. Ubuntu hasn't shipped a fix, and none is in progress for the Spark's kernel yet. What to do 👇
