In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: dsa: sja1105: flower: reject cross-chip redirect<\/p>\n
dsa_port_from_netdev() may return a valid port from a different switch
\nchip. Programming another chip’s port index into the local hardware
\ncauses redirection to the wrong port, or an out-of-bounds access if the
\nindex exceeds the local chip’s port count.<\/p>\n
Apply a minimal fix that adds a check to catch this case and adjusts the
\nextack message. When cls->common.skip_sw is not set, the operation could
\ninstead redirect to the upstream port and let the software or upstream
\nswitch(es) handle the forward, but that is not addressed here.<\/p>\n","protected":false},"excerpt":{"rendered":"
