In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: ethernet: cortina: Make RX SKB per-port<\/p>\n
The SKB used to assemble packets from fragments in gmac_rx()
\nis static local, but the Gemini has two ethernet ports, meaning
\nthere can be races between the ports on a bad day if a device
\nis using both.<\/p>\n
Make the RX SKB a per-port variable and carry it over between
\ninvocations in the port struct instead.<\/p>\n
Zero the pointer once we call napi_gro_frags(), on error (after
\ncalling napi_free_frags()) or if the port is stopped.<\/p>\n
Zero it in some place where not strictly necessary just to
\nemphasize what is going on.<\/p>\n
