In the Linux kernel, the following vulnerability has been resolved: mmc: jz4740: Apply DMA engine limits to maximum segment size Follow the approach used in other DMA-enabled MMC host drivers see host/mmci.c, and limit the maximum segment size based on the capabilities of the DMA engine. This is...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/shmem-helper: The erroneous “put” operation has been removed from the error path. The drmgemshmemmmap function does not have a reference in the error code path, resulting in the dma-buf shmem GEM object being freed...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Firmware: armffa – Set dmamask for FFA devices. Setting dmamask for FFA devices is necessary; otherwise, DMA allocation using the device pointer may lead to the following warning: WARNING: CPU: 1, PID: 1, at...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Ensure that the skb is freed when it is completely used. By using the TX BD to track the skb pointer, we can efficiently free the skb buffer after a frame has been transmitted. However, to avoid freeing the skb whil...
