Linux hwe edge: 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… (CVE-2026-23389)
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.
AI Analysis
Technical Summary
The Linux kernel's ice driver contained a memory leak in the ice_set_ringparam() function. Specifically, tx_rings and xdp_rings are allocated before rx_rings, but if rx_rings allocation fails, the code jumps to a label that leaks both tx_rings and xdp_rings. Additionally, if setup of an individual Rx ring fails, tx_rings are freed but xdp_rings are leaked. The fix introduces a new free_xdp label and updates error handling paths to ensure proper freeing of both xdp_rings and tx_rings on failure. This vulnerability was discovered via static analysis and code review and has been resolved in Linux kernel versions 6.8.0-1061.64~22.04.1 and later.
Potential Impact
The vulnerability causes a memory leak in the Linux kernel's ice driver, which can degrade system availability by exhausting memory resources over time. There is no impact on confidentiality or integrity. The CVSS vector indicates local attack with low complexity and privileges required, no user interaction, and an availability impact.
Mitigation Recommendations
A patch is available and users should update to Linux kernel versions 6.8.0-1061.64~22.04.1 or later as provided by the vendor. After updating, a system reboot is required to apply the fix. No additional mitigation is necessary as the issue is resolved by the official update.

Technical Analysis
The Linux kernel's ice driver contained a memory leak in the ice_set_ringparam() function. Specifically, tx_rings and xdp_rings are allocated before rx_rings, but if rx_rings allocation fails, the code jumps to a label that leaks both tx_rings and xdp_rings. Additionally, if setup of an individual Rx ring fails, tx_rings are freed but xdp_rings are leaked. The fix introduces a new free_xdp label and updates error handling paths to ensure proper freeing of both xdp_rings and tx_rings on failure. This vulnerability was discovered via static analysis and code review and has been resolved in Linux kernel versions 6.8.0-1061.64~22.04.1 and later.

The vulnerability causes a memory leak in the Linux kernel's ice driver, which can degrade system availability by exhausting memory resources over time. There is no impact on confidentiality or integrity. The CVSS vector indicates local attack with low complexity and privileges required, no user interaction, and an availability impact.
