Lifecycle Timeline
1DescriptionNVD
Due to Improper Access Control of NAND-based EFS in Snapdragon Automobile, Snapdragon Mobile and Snapdragon Wear, From fastboot on a NAND-based device, the EFS partition can be erased. Apps processor then has non-secure world full read/write access to the partition until the modem boots and configures the EFS partition addresses in its MPU partition.
AnalysisAI
Due to Improper Access Control of NAND-based EFS in Snapdragon Automobile, Snapdragon Mobile and Snapdragon Wear, From fastboot on a NAND-based device, the EFS partition can be erased. Rated high severity (CVSS 7.7), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Incorrect Permission Assignment (CWE-732), which allows attackers to access resources due to misconfigured permissions. Due to Improper Access Control of NAND-based EFS in Snapdragon Automobile, Snapdragon Mobile and Snapdragon Wear, From fastboot on a NAND-based device, the EFS partition can be erased. Apps processor then has non-secure world full read/write access to the partition until the modem boots and configures the EFS partition addresses in its MPU partition. Affected products include: Qualcomm Mdm9206 Firmware, Qualcomm Mdm9607 Firmware, Qualcomm Mdm9635M Firmware, Qualcomm Mdm9640 Firmware, Qualcomm Mdm9650 Firmware.
RemediationAI
