Memory Leak in Linux Kernel ice_set_ringparam Function

Publication date: 2026-03-25

Assigner: kernel.org

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.

Mitigation Strategies

The vulnerability is fixed by updating the Linux kernel to a version where the ice driver properly frees allocated memory in ice_set_ringparam(). Therefore, the immediate step to mitigate this vulnerability is to apply the patch or upgrade to a Linux kernel version that includes this fix.

Executive Summary

This vulnerability exists in the Linux kernel's ice driver, specifically in the function ice_set_ringparam(). The issue is a memory leak caused by improper handling of allocated resources when certain allocations or setups fail.

In detail, tx_rings and xdp_rings are allocated before rx_rings. If the allocation of rx_rings fails, the code jumps to a label that causes tx_rings and xdp_rings to be leaked (not freed). Additionally, if setting up an individual Rx ring fails during a loop, the code frees tx_rings but leaks xdp_rings.

The fix involves introducing a new label to properly free xdp_rings and updating error handling paths to ensure that both xdp_rings and tx_rings are freed correctly if rx_rings allocation or setup fails.

Impact Analysis

This vulnerability can lead to memory leaks in the Linux kernel when using the ice driver. Memory leaks can cause increased memory usage over time, potentially leading to degraded system performance or instability.

In environments where the ice driver is heavily used, this could result in resource exhaustion, requiring system reboots or interventions to recover memory.
