CVE-2026-43500

Summary: CVE-2026-43500 affects the Linux kernel RXRPC path for DATA/RESPONSE packets. The issue occurs when skb fragments are externally owned (e.g., via splice() or frag lists) and the code path decrypts in place, binding frag pages into the AEAD/skcipher SGL. The fix extends the gate to unshar...
