- Summary
- vsock: fix recursive ->recvmsg calls
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
vsock: fix recursive ->recvmsg calls
After a vsock socket has been added to a BPF sockmap, its prot->recvmsg has been replaced with vsockbpfrecvmsg(). Thus the following recursiion could happen:
vsockbpfrecvmsg() -> _vsockrecvmsg() -> vsockconnectiblerecvmsg() -> prot->recvmsg() -> vsockbpfrecvmsg() again
We need to fix it by calling the original ->recvmsg() without any BPF sockmap logic in _vsockrecvmsg().
