Privileged disclosure of protected SMM memory address
Published Jul 16, 2026 · Updated Jul 16, 2026
Information disclosure in affected Lenovo notebook BIOS versions allows local users with high privileges to reveal a protected SMM memory address. Lenovo has not published the faulty handler, variable, or operation that exposes the System Management Mode address. Exploitation requires local high privileges and reveals an address rather than protected SMM contents or modification capability.
