Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iouring/net: Ensure that the import of the vectorized buffer node is tied to the notification. When support for vectorized registered buffers was added, the import itself uses ‘req’ instead of the notification iokiocb, sr-notif...

kernel: io_uring/rsrc: reject zero-length fixed buffer import

A flaw was found in the Linux kernel's iouring subsystem. A local attacker can exploit a vulnerability in the ioimportfixed function by importing a zero-length fixed buffer. This can lead to an out-of-bounds read from slab memory, potentially resulting in information disclosure or a denial of...

CVE-2026-43006

CVE-2026-43006 (Linux kernel io_uring rsr/rsrc): A zero-length fixed-buffer import in io_import_fixed() could trigger a slab-out-of-bounds read due to a boundary check that allows len == 0 to be processed. The underlying issue is in validate_fixed_range(), which permits buf_addr at the end of the...

CVE-2025-68294

Summary : CVE-2025-68294 concerns the Linux kernel’s IO_URING/vectored buffer handling. The issue arises in the vectored buffer import path where the import used the wrong IO_kiocb context ('req') instead of the notification context (sr->notif), risking lifetime misalignment between the vector...
