CVE-2026-45839

CVE-2026-45839 is a Linux kernel vulnerability where negative CO-RE accessor indices in bpf_core_parse_spec() could cause an out-of-bounds read, leading to a deterministic kernel crash during BPF program load on systems with CONFIG_DEBUG_INFO_BTF=y. The issue arises because sscanf parses componen...
