Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: L2CAP: Fixed a division by zero issue in l2capleflowctlinit. l2capleflowctlinit may cause both a division by zero and an integer overflow, as hdev-lemtu may not fall within the valid range. The MTU value was moved...

CVE-2026-80793

In the Linux kernel, the following vulnerability has been resolved: ipv4: reject undersized MTUs in ipdofragment ipdofragment subtracts the IPv4 header length from the effective MTU and passes the resulting payload MTU to ipfragnext. If the effective MTU is smaller than hlen + 8, ipfragnext round...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Added validation for MTU changes Increasing the MTU beyond the HDS threshold causes the hardware to fragment packets across multiple buffers. If a single-buffer XDP program is attached, the driver will drop all...

CVE-2026-45952

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Add validation for MTU changes Increasing the MTU beyond the HDS threshold causes the hardware to fragment packets across multiple buffers. If a single-buffer XDP program is attached, the driver will drop all multi-fr...

CVE-2026-45952

The CVE-2026-45952 issue affects the Linux kernel fbnic driver. It concerns MTU changes when an XDP program is attached: increasing MTU beyond the hardware threshold can cause fragmentation across multiple buffers, and the driver will drop all multi-fragment frames for single-buffer XDP. This can...
