Frequently Asked Questions

1

Who can exploit this issue?

The provided vector indicates local access and low privileges are required. No user interaction is required.

2

What systems should be prioritized for review?

Review Ubuntu systems using the listed kernel packages: linux, linux-realtime, linux-azure, linux-gcp, linux-gke, linux-riscv, linux-fips, or linux-azure-fde. The issue is in the kernel's MPTCP TCP handling.

3

How might existing impact be identified?

Look for kernel warnings involving __mptcp_move_skbs_from_subflow in net/mptcp/protocol.c, particularly messages associated with DSS corruption during large PMTU transmission. The supplied report also shows a TCP SYN-flooding warning, but does not establish that it alone confirms exploitation.
