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...

CVE-2026-31778

Summary: CVE-2026-31778 affects the Linux kernel ALSA caiaq driver (init_card) and is caused by an off-by-one in a whitespace-stripping loop that copies a card id. The 16-byte local buffer can be filled without leaving space for the terminating null, causing a non-null-terminated string to be pas...

CVE-2026-31772

The CVE-2026-31772 issue affects the Linux kernel Bluetooth HCI path. The root cause is a stack buffer overflow in hci_le_big_create_sync where DEFINE_FLEX allocates a stack struct for BIS entries with room for 17, but conn->num_bis can be up to 31, leading to a memcpy that can write beyond th...
