CVE-2026-64354

The CVE-2026-64354 entry concerns the Linux kernel BPF component, specifically btf_repeat_fields() handling of user-supplied BTF data during BPF_BTF_LOAD. A malformed BTF can trigger an integer overflow when calculating the expanded field count, allowing a heap out-of-bounds write past the fixed ...
