DescriptionNVD

In the Linux kernel, the following vulnerability has been resolved:

net: mscc: ocelot: Fix crash when adding interface under a lag

Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag") fixed a similar issue in the lan966x driver caused by a NULL pointer dereference. The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic and is susceptible to the same crash.

This issue specifically affects the ocelot_vsc7514.c frontend, which leaves unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as it uses the DSA framework which registers all ports.

Fix this by checking if the port pointer is valid before accessing it.

AnalysisAI

The ocelot network driver in the Linux kernel is susceptible to a null pointer dereference crash when adding a network interface under a link aggregation group, affecting systems using the ocelot_vsc7514 frontend. A local attacker with unprivileged access can trigger this denial of service condition by performing specific network interface configuration operations. A patch is available that adds proper pointer validation before accessing port structures.

Technical ContextAI
