CVE-2026-43173

A flaw was found in the Linux kernel. A local user can trigger a NULL pointer dereference in the ixp4xx_get_ts_info() function within the network ethernet xscale driver. This occurs because ixp46x_ptp_find() is unconditionally called, even on systems that do not support the ixp46x PTP feature. Successful exploitation of this vulnerability leads to a kernel crash, resulting in a Denial of Service (DoS).
