CVE-2026-43406

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> libceph: prevent potential out-of-bounds reads in process_message_header()<br /> <br /> If the message frame is (maliciously) corrupted in a way that the<br /> length of the control segment ends up being less than the size of the<br /> message header or a different frame is made to look like a message<br /> frame, out-of-bounds reads may ensue in process_message_header().<br /> <br /> Perform an explicit bounds check before decoding the message header.
