Double free in Linux kernel - CVE-2026-53009

Vulnerability identifier: #VU135349

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-53009

CWE-ID: CWE-415

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a double free in ice_xmit_frame_ring() and tx ring buffer cleanup when handling transmit error paths and interface shutdown. A local user can trigger transmit checksum or tso failure conditions and then bring the interface down to cause a denial of service.

The issue occurs because a tx_buf entry can remain marked as valid and continue to reference an skb that was already freed in the error path.
