In the Linux kernel, the following vulnerability has been resolved: Avoiding hwdesc array overrun in dw-axi-dmac I have a use case where nrbuffers = 3, and each descriptor consists of 3 segments. As a result, the DMA channel descriptors allocated are 9. Since axidescput handles the hwdesc by...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fixed the issue with the ib block iterator counter overflow. When registering a new DMA MR after selecting the best aligned page size for it, we iterate over the given sglist to split each entry into smaller, aligned D...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

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...
