kernel: Linux kernel: Denial of Service vulnerability in RDMA/rxe component

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe component. A local user could trigger a kernel panic by causing an error during the setup of a Queue Pair QP in rxecreateqp. This occurs when the system attempts to clean up resources by...

kernel: RDMA/efa: Fix wrong resources deallocation order

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix wrong resources deallocation order When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If t...

kernel: RDMA/irdma: Fix data race on CQP completion stats

The Linux kernel contains a race condition vulnerability in its RDMA/irdma subsystem, where completion queue pair CQP completion statistics are read concurrently without adequate synchronization while being updated on another CPU. Under certain workloads, a lack of atomic operations and improper...

kernel: Linux kernel: Denial of Service in RDMA/bnxt_re driver due to race condition during QP destruction

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA bnxtre driver. A local user could exploit a race condition that occurs when a Queue Pair QP is destroyed, but completion queue CQ polling continues. This can lead to a kernel panic, resulting in a Denial of Service DoS on the...

kernel: RDMA/cma: Allow UD qp_type to join multicast only

In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Allow UD qptype to join multicast only As for multicast: - The SIDR is the only mode that makes sense; - Besides PSUDP, other port spaces like PSIB is also allowed, as it is UD compatible. In this case qkey also needs t...

kernel: RDMA/rxe: Fix "kernel NULL pointer dereference" error

A NULL pointer dereference vulnerability was found in the RXE Soft-RoCE RDMA driver in the Linux kernel. When rxequeueinit fails during queue pair initialization in rxeqpinitreq, the task function and argument pointers qp-req.task.func and qp-req.task.arg remain uninitialized. The cleanup functio...
