Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: mscc: ocelot: Fix crash when adding interface under a lag<br /> <br /> Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag")<br /> fixed a similar issue in the lan966x driver caused by a NULL pointer dereference.<br /> The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic<br /> and is susceptible to the same crash.<br /> <br /> This issue specifically affects the ocelot_vsc7514.c frontend, which leaves<br /> unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as<br /> it uses the DSA framework which registers all ports.<br /> <br /> Fix this by checking if the port pointer is valid before accessing it.
