Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the Linux kernel’s implementation of RDMA over InfiniBand. An attacker with a privileged local account can leak kernel stack information by issuing commands to the /dev/infiniband/rdmacm device node. Although this access is unlikely to reveal sensitive user information, i...

CVE-2026-43120

In the Linux kernel RDMA/irdma driver, CVE-2026-43120 describes a double-free during rereg_user_mr when IB_MR_REREG_TRANS is set. If the trans reg path fails after allocating a new umem, the code releases it but fails to NULL the iwmr->region, causing ib_umem_release to be invoked again during...
