Description
In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: Add a check for oversized packets Occasionnaly we may get oversized packets from the hardware which exceed the nomimal 2KiB buffer size we allocate SKBs with. Add an early check which drops the packet to avoid invoking skb_over_panic() and move on to processing the next packet.

Executive Summary

This vulnerability occurs in the Linux kernel's bcmgenet network driver where oversized packets from hardware can exceed the allocated 2KiB buffer size for socket buffers (SKBs). Without proper checks, these oversized packets can cause a panic in the kernel (skb_over_panic). The fix adds an early check to drop such oversized packets to prevent this panic and allow normal processing of subsequent packets.

Impact Analysis

If exploited or triggered, this vulnerability can cause the Linux kernel to panic due to oversized network packets, potentially leading to system instability or denial of service by crashing the kernel or disrupting network operations.
