AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The fix involves validating port pointers before access to prevent the crash. Users should update to patched kernel versions as provided by their Linux distribution vendors. No additional mitigation is required beyond applying the official fix.
Description
A vulnerability in the Linux kernel's mscc ocelot driver caused a crash when adding an interface under a link aggregation group (LAG) due to a NULL pointer dereference. The issue affects the ocelot_vsc7514.c frontend, which leaves unused ports as NULL pointers, unlike the unaffected felix_vsc9959.c frontend. This flaw was fixed by adding a check for valid port pointers before access. The vulnerability has a medium severity score and does not impact confidentiality or integrity but can cause denial of service via a crash.
