Official Description

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.
