CVE-2026-43406
概要

In the Linux kernel, the following vulnerability has been resolved:

libceph: prevent potential out-of-bounds reads in process_message_header()

If the message frame is (maliciously) corrupted in a way that the
length of the control segment ends up being less than the size of the
message header or a different frame is made to look like a message
frame, out-of-bounds reads may ensue in process_message_header().

Perform an explicit bounds check before decoding the message header.
