CVE-2026-98275

A flaw was found in the Linux kernel's Cortina Ethernet driver. This flaw may result in a Denial of Service DoS when a network receive buffer overrun occurs. Due to an incorrect bit calculation, the interrupt service routine acknowledges the wrong register bit, leaving the overrun interrupt...

Astra Linux – vulnerability in linux-6.1, linux-6.12

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Carry over frag counter The gmacrx NAPI poll function assembles packets in an SKB from a ring buffer.
