Bullshark on Narwhal: Implementation-Level Workflow Analysis of Round-Based DAG Consensus in Theory and Practice

Round-based DAGs enable high-performance Byzantine fault-tolerant consensus, yet their technical advantages remain underutilized due to their short history. While research on consensus protocols is active in both academia and industry, many studies overlook implementation-level algorithms, leavin...

In the Linux kernel, the following vulnerability has been resolved: cifs: fix small mempool leak in SMB2negotiate In some cases of failure dialect mismatches in SMB2negotiate, after the request is sent, the checks would return -EIO when they should be rather setting rc = -EIO and jumping to negex...

CVE-2022-49938

CVE-2022-49938 is a Linux kernel vulnerability in the CIFS SMB2_negotiation path. The issue is a small mempool leak in SMB2_negotiate() where, on certain dialect-mismatch failures, the code could exit without freeing the response buffer from mempool due to an incorrect -EIO handling. The fix tigh...
