- Summary
- mptcp: fix NULL pointer dereference on fastopen early fallback
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix NULL pointer dereference on fastopen early fallback
In case of early fallback to TCP, subflowsynrecv_sock() deletes the subflow context before returning the newly allocated sock to the caller.
The fastopen path does not cope with the above unconditionally dereferencing the subflow context.
