In the Linux kernel, the following vulnerability has been resolved: iommu/sprd: The DMA buffer should be released to avoid memory leaks. When attaching to a domain, the driver allocates a DMA buffer, which is used to store the address mapping table. This buffer must be released when the IOMMU...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fixed the Rx DMA data size and skboverpanic issue. The function managetrxbufcfg aligns the DMA data size of the RX buffer to be a multiple of 64. As a result, a packet slightly larger than mtu+14, for example, 1536...

In the Linux kernel, the following vulnerabilities have been resolved: drm/panthor: Fix for dma-fence safe access rules Commit 506aa8b02a8d6 “dma-fence: Add safe access helpers and document the rules” details the dma-fence safe access rules. The most common issue is that...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: caam – fixed an overflow issue when dealing with long HMAC keys. When a key that is longer than the block size is provided, it is copied and then hashed into the actual key. The memory allocated for the copy needs to be...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: nvmem: zynqmpnvmem: Fixed the buffer size in DMA and memcpy. The buffer size used in DMA allocation and memcpy is incorrect. This can lead to undersized DMA buffer accesses and potential memory corruption. Use the correct buff...
