Securing High-Performance Data Transfers: Implementing AES Encryption in RDMA Systems

Remote Direct Memory Access RDMA is a key enabler of high-performance systems, offering low latency, high throughput, and reduced CPU overhead by allowing direct memory-to-memory transfers between machines. However, its design bypasses traditional CPU-mediated security mechanisms, introducing...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/rds: fixed the possible null dereference of cp The cp parameter may be null. Calling cp-cpconn would result in a null dereference. Simon Horman adds: Analysis: cp is a parameter of rdsrdmamap, and it is not reassigned. The...

Astra Linux – Vulnerability in Xen

A issue was discovered in Xen through version 4.11.x, allowing users of x86 Intel HVM guest operating systems to obtain unintended read/write DMA access. This could potentially lead to a denial of service host operating system crash or privilege escalation. This issue arises because a backport...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: HID: Intel-thc-hid: Added a safety check for reading the DMA buffer. A readiness check for the DMA buffer is added before reading it, to avoid unexpected NULL pointer accesses...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: A potential null-ptr-deref occurred in passestablish. If getepfromtid fails to find a non-NULL value for ep, ep will be dereferenced later, regardless of whether it is empty. This patch adds a simple sanity check to f...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: lantiq – Fix for memory corruption in the RX ring. In situations where memory allocation or DMA mapping fails, an invalid address may be programmed into the descriptor. This can lead to memory corruption. If memory allocatio...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dma-debug: prevents an error message from causing runtime problems. For some drivers that use the DMA API, this error message can occur several million times per second. This can lead to excessive use of the kernel’s printk buffe...
