The vulnerability of the xdma_probe() function in the drivers/dma/xilinx/xdma.c driver module of the Linux operating system’s DMA engine allows a hacker to cause a service failure.

The vulnerability of the xdmaprobe function in the drivers/dma/xilinx/xdma.c file of the Linux kernel’s DMA driver module is related to errors in error handling. Exploiting this vulnerability could allow an attacker to cause a system failure...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: dmaengine: xilinx: xdma: Fixed regmap maxregister The maxregister field is assigned the size of the register memory region, rather than the offset of the last register. As a result, reading from the regmap via debugfs can cause a...
