CVE-2026-74263

The CVE affects the Linux kernel net: wwan: t7xx driver. In t7xx_port_ctrl_tx, each skb fragment is cloned and the clone is immediately used to set cloned->len; if skb_clone() fails, a NULL pointer dereference can occur. The fix checks the clone before using it and, when previous fragments are...
