Linux Distros Unpatched Vulnerability : CVE-2026-31691

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - igb: remove napisynchronize in igbdown When an AFXDP zero-copy application terminates abruptly e.g., kill -9, the XSK buffer pool is destroyed but NAPI polling...

CVE-2026-31691

A flaw was found in the Linux kernel's igb network driver. When an AFXDP zero-copy application terminates abruptly, the network driver's NAPI polling mechanism can become stuck. This prevents the igbdown function from completing, leading to the TX queue becoming permanently stalled. This can resu...
