A Simulation-Based Evaluation Framework for Inter-VM RowHammer Mitigation Techniques

Inter-VM RowHammer is an attack that induces a bitflip beyond the boundaries of virtual machines VMs to compromise a VM from another, and some software-based techniques have been proposed to mitigate this attack. Evaluating these mitigation techniques requires to confirm that they actually mitiga...

CVE-2024-43102

Concurrent removals of certain anonymous shared memory mappings by using the UMTXSHMDESTROY sub-request of UMTXOPSHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTXSHMDESTROY...

CVE-2024-43102

CVE-2024-43102 describes a kernel-level issue in FreeBSD involving concurrent removals of anonymous shared memory mappings via the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM. The root cause is that the reference count for the mapping object can be decremented too many times, causing premature fr...
