CVE-2022-49433

The CVE-2022-49433 entry is confirmed with concrete details in connected advisories: in the Linux kernel RDMA/hfi1 driver, a path may call hfi1_free_devdata() with sdma_map_lock uninitialized if probe of hfi1 fails before sdma_map_lock is set up. This could lead to locking operations being perfor...

CVE-2022-49404

The CVE-2022-49404 entry concerns the Linux kernel RDMA/hfi1 path. The root cause is an integer multiplication overflow during inter-packet delay calculations due to type-conversion order, allowing overflow and an incorrect result. The fix forces one operand to be u64 so the promotion occurs befo...
