Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: nvmet-tcp: bounds checks were added in nvmettcpbuildpduiovec. The nvmettcpbuildpduiovec function could exceed the range of cmd-req.sg when the PDU length or offset exceeds sgcnt, and then use absurd values for sg-length/offset...

CVE-2026-64124

CVE-2026-64124 concerns the Linux kernel net: devmem: bind via dma-buf with non-page-aligned size or SG length. The issue arises because net_devmem_bind_dmabuf() trusts dmabuf->size and sg_dma_len() to be multiples of PAGE_SIZE without checking, causing an out-of-bounds access: tx_vec is sized...
