CVE-2022-49378

In the Linux kernel, the following vulnerability has been resolved: sfc: fix considering that all channels have TX queues Normally, all channels have RX and TX queues, but this is not true if modparam efxseparatetxchannels=1 is used. In that cases, some channels only have RX queues and others onl...

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...

CVE-2024-50094

CVE-2024-50094 : Linux kernel vulnerability in the sfc driver where netpoll incorrectly called xdp_do_flush() with a budget of zero, causing a crash because bpf_net_context was never assigned. The fix conditionally invokes xdp_do_flush() only when budget is non-zero, mitigating the crash in netpo...
