CVE-2023-54037

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

ice: prevent NULL pointer deref during reload

Calling ethtool during reload can lead to call trace, because VSI isn't configured for some time, but netdev is alive.

To fix it add rtnl lock for VSI deconfig and config. Set ::num_q_vectors to 0 after freeing and add a check for ::tx/rx_rings in ring related ethtool ops.

Add proper unroll of filters in ice_start_eth().

Reproduction: $watch -n 0.1 -d 'ethtool -g enp24s0f0np0' $devlink dev reload pci/0000:18:00.0 action driver_reinit
