ice: Fix memory leak in ice_set_ringparam()

Assigner: Linux
Reserved: 13.01.2026 Published: 25.03.2026 Updated: 25.03.2026

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

ice: Fix memory leak in ice_set_ringparam()

In ice_set_ringparam, tx_rings and xdp_rings are allocated before rx_rings. If the allocation of rx_rings fails, the code jumps to the done label leaking both tx_rings and xdp_rings. Furthermore, if the setup of an individual Rx ring fails during the loop, the code jumps to the free_tx label which releases tx_rings but leaks xdp_rings.

Fix this by introducing a free_xdp label and updating the error paths to ensure both xdp_rings and tx_rings are properly freed if rx_rings allocation or setup fails.

Compile tested only. Issue found using a prototype static analysis tool and code review.
