Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the dhara_nand_read process when a flash read error occurs during journal resume. An attacker can cause a kernel fault and denial of service by providing a corrupted or crafted on-flash image, or by inducing faults or wear on the NAND medium. This is only exploitable if the NAND medium contains errors or is manipulated to trigger a flash read error during disk initialization or mounting.
