AI-suggested

A fix is available and has been applied in the Linux kernel source code as indicated by multiple fixed commit versions. Users should update their Linux kernel to a version including these fixes to prevent the crash. No additional mitigation is required beyond applying the official fix.

Description

A vulnerability in the Linux kernel's ocelot driver causes a crash when adding an interface under a link aggregation group (lag). The issue arises from dereferencing NULL pointers for unused ports in the ocelot_vsc7514.c frontend. This has been fixed by adding checks for valid port pointers before access. The lan966x driver had a similar issue fixed previously. The felix_vsc9959.c frontend is not affected due to its use of the DSA framework.
