Description
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.
Affected configurations
• linux linux kernel (>= 5.12 < 5.15.198)
• linux linux kernel (>= 5.16 < 6.1.161)
• linux linux kernel (>= 6.2 < 6.6.121)
• linux linux kernel (>= 6.7 < 6.12.66)
• linux linux kernel (>= 6.13 < 6.18.6)
• linux linux kernel 6.19
