CVE-2026-43020

CVE-2026-43020 concerns the Linux kernel Bluetooth MGMT path: load-time Long Term Keys can overflow a fixed-size stack buffer if enc_size exceeds the 16-byte key buffer. The root cause is validation of enc_size not rejecting oversized values during management LTK record validation, allowing inval...
