First published: Fri Nov 08 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: mptcp: handle consistently DSS corruption Bugged peer implementation can send corrupted DSS options, consistently hitting a few warning in the data path. Use DEBUG_NET assertions, to avoid the splat on some builds and handle consistently the error, dumping related MIBs and performing fallback and/or reset according to the subflow type.
