Memory disclosure via TpmSetup out-of-bounds read
Published Apr 11, 2025 · Updated Apr 11, 2025
Out-of-bounds read in Lenovo System x3550 M5 before 4.40 and System x3560 M5 before 4.20 allows local users to read memory. The TpmSetup module fails to validate input before reading beyond an intended buffer, but Lenovo has not disclosed the affected function or input field. Exploitation requires local access and elevated privileges; the reported consequence is memory disclosure without integrity or availability impact.
