Root-Cause Analysis & Kernel Hardening: CVE-2026-31431
Analyze CVE-2026-31431 at the source: understand the CWE-669 cross-sphere flaw in the kernel's AF_ALG AEAD interface and the out-of-place upstream fix, then patch and apply defense-in-depth hardening (module blacklist, restricted user namespaces) and verify the posture.

Root-Cause Analysis & Kernel Hardening: CVE-2026-43284 & CVE-2026-43500
Analyze two related Linux kernel CVEs (CVE-2026-43284 and CVE-2026-43500) at the source: recognize the shared root cause (in-place decryption over shared socket-buffer fragments) across IPsec/ESP and RxRPC, read both upstream fixes, then patch both with one update and apply defense-in-depth hardening for both subsystems, and verify.
