CVE-2026-53008

A flaw was found in the Linux kernel. A race condition exists in the ice network driver's TX timestamp ring cleanup, specifically between the ice_free_tx_tstamp_ring() and ice_tx_map() functions. This vulnerability could allow a local attacker to trigger a null pointer dereference, leading to a system crash and a Denial of Service (DoS).

This vulnerability is rated as Moderate because exploitation is confined to a local denial of service via a kernel crash, without exposing confidential data or permitting arbitrary code execution. The flaw specifically affects environments utilizing Intel E800 series network interface hardware managed by the ice driver. Triggering the race condition requires local access and precise concurrency during packet transmission and queue teardown operations. Systems lacking this hardware or running kernels without this driver loaded are unaffected.
