Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-axi-dmac: Do not print NULL LLI during an error. During debugging, we encountered an issue where the axichandumplli function was passed a NULL LLI pointer, which ultimately caused an OOPS error due to attempts to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dma-axi-dmac: The use of a DMA pool to manage DMA descriptors has been implemented. For architectures like Microblaze or Arm64 where this API is used, DMADIRECTREMAP is set, which means that dmaalloccoherent may remap...

CVE-2026-72474

A flaw was found in the Linux kernel's dma-axi-dmac component. Under specific conditions on architectures like Microblaze or arm64, a memory management error can occur when the system attempts to free Direct Memory Access DMA coherent memory from a soft interrupt softirq context. This improper...

CVE-2026-72475

A flaw was found in the Linux kernel's dma-axi-dmac component. This vulnerability arises from the improper freeing of a data structure within the axidmacprepperipheraldmavec function. This oversight could lead to memory corruption, potentially causing system instability or a denial of service...
