CVE-2024-32633

Incorrect eMMC full-disk test via unsigned comparison

Published Apr 16, 2024 · Updated Aug 20, 2024

Logic error in ASR Falcon/Crane before CP01.057.067 allows physically proximate attackers to cause unspecified impact during eMMC full-disk testing. The eMMC full-disk test compares an unsigned value with zero as though it could be negative, forcing the condition to evaluate the same way. Physical access is required, and ASR has not disclosed how the invariant test result exposes data or interrupts the device.
