CVE-2026-72393

A flaw was found in the Linux kernel's fbnic Ethernet driver. When the fbnictxlso function reallocates a socket buffer skb, it fails to update a cached pointer to shared information. This can lead to a use-after-free vulnerability, where the driver attempts to access memory that has already been...

CVE-2026-45952

A flaw was found in the Linux kernel's fbnic driver. This vulnerability allows a local user to cause a Denial of Service DoS by increasing the Maximum Transmission Unit MTU beyond the hardware's threshold while an eXpress Data Path XDP program is attached. This improper validation of MTU changes...

CVE-2026-45977

A flaw was found in the Linux kernel's fbnic Fibre Channel over Ethernet Network Interface Card driver. A race condition exists in the handling of firmware logs, where the log can be freed while still being accessed. This can lead to a use-after-free vulnerability, potentially allowing an attacke...

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...
