CVE-2022-49096

The CVE-2022-49096 issue in the Linux kernel affects the sfc (Solarflare) network driver: after ethtool -G changes to rx/tx ring buffer sizes, the driver reallocates/reinitializes queues but fails to reinitialize the XDP TX queues (efx->xdp_tx_queues). This can lead to the XDP path using an un...
