CVE-2026-110661
Published:October 14, 2026
Updated:October 15, 2026
CGNS through 4.5.2 contains a stack out-of-bounds read vulnerability in ADFI_read_node_header that allows attackers to crash applications by supplying crafted ADF node headers. Attackers can craft .cgns or .adf files whose non-NUL-terminated end tag causes ADFI_stridx_c to scan past disk_node_data, crashing tools like cgnslist.
