Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: comedi: dt9812 – fixed DMA buffers on the stack. USB transfer buffers are typically mapped for DMA operations, and they must not be allocated on the stack; otherwise, transfers will fail. Proper transfer buffers should be allocat...

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...

In the Linux kernel, the following vulnerability has been resolved: dma: Fixed the call order in dmamfreecoherent. dmamfreecoherent frees a DMA allocation, making the freed vaddr available for reuse. Then, it calls devresDestroy to remove and free the data structure used to track the DMA...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: safexcel – Added error handling for dmamapsg calls The Macro dmamapsg may return 0 in the event of an error. This patch enables checks in case of a macro failure and ensures that previously mapped buffers are unmapped usi...

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...
