This affects the function _bfd_elf_eh_frame_section_offset of the file bfd/elf-eh-frame.c of the component Eh Frame Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet.","severity":{"version":"4.0","score":4.8,"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.0017,"percentile":0.0641,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-404","CWE-476"],"published":"2026-09-15T08:15:22Z","modified":"2026-11-05T05:40:51Z","affected":[{"source":"osv","ecosystem":"Azure
