- Summary
- smb: server: let send_done handle a completion without IB_SEND_SIGNALED
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb: server: let send_done handle a completion without IB_SEND_SIGNALED
With smbdirect_send_batch processing we likely have requests without IB_SEND_SIGNALED, which will be destroyed in the final request that has IB_SEND_SIGNALED set.
If the connection is broken all requests are signaled even without explicit IB_SEND_SIGNALED.
