CVE-2026-64026

CVE-2026-64026 affects the Linux kernel’s rxrpc path. The issue was addressed by removing in-place decryption in splice()-transmitted DATA packets and instead unconditionally copying the packet content into a dedicated bounce buffer, which is decrypted there and then copied to the final destinati...
