CVE-2024-0646: High Fixes for in Linux Kernel

First published: Sun Dec 10 2023(Updated: )

A flaw in the Linux Kernel found. When splice() is called with a ktls socket as destination, the ktls code fails to update the internal "curr"/"copybreak" accounting that tracks which parts of the plaintext scatter-gather buffer (`struct sk_msg_sg`) are unused writable memory. This can cause subsequent writes to the socket to overwrite the contents of spliced pages, including pages from files to which the caller is not supposed to have write access.
