CVE-2026-90104

CVE-2026-90104 affects the Linux kernel's NFSv4.1 callback handling. In decode_cb_sequence_args(), the csa_rclists array is allocated with kmalloc_objs(), leaving referring_call_list entries uninitialized. Because decode_rc_list() only assigns rcl_refcalls when the list is non-empty, a valid empt...
