CVE-2022-49606

CVE-2022-49606 affects the Linux kernel RDMA/irdma path. The issue is a sleep (mutex) operation taken to process RoCEv2 QPs on netdev events, which can trigger a BUG: sleeping function called from invalid context in mutex_lock and lead to a kernel crash. The fix removes RoCEv2 handling in irdma_c...

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-2022-49433 RDMA/hfi1: Prevent use of lock before it is initialized

In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Prevent use of lock before it is initialized If there is a failure during probe of hfi1 before the sdmamaplock is initialized, the call to hfi1freedevdata will attempt to use a lock that has not been initialized. If th...

In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Prevent panic when SDMA is disabled If the hfi1 module is loaded with HFI1CAPSDMA off, a call to hfi1writeiter will dereference a NULL pointer and panic. A typical stack frame is: sdmaselectuserengine hfi1...

CVE-2022-49429

CVE-2022-49429 affects the Linux kernel’s RDMA/hfi1 subsystem. When the hfi1 module is loaded with SDMA disabled (HFI1_CAP_SDMA off), a call to hfi1_write_iter() can dereference a NULL pointer, causing a kernel panic through the I/O path (sdma_select_user_engine → hfi1_user_sdma_process_request →...

CVE-2022-49404 RDMA/hfi1: Fix potential integer multiplication overflow errors

In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Fix potential integer multiplication overflow errors When multiplying of different types, an overflow is possible even when storing the result in a larger type. This is because the conversion is done after the...

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...
