CVE-2026-43020

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: validate LTK encsize on load Load Long Term Keys stores the user-provided encsize and later uses it to size fixed-size stack operations when replying to LE LTK requests. An encsize larger than the 16-byte key...

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...
