CriticalCVSS 9.3
Published: Translated: NVD NIST

Summary

In the UFS Field Firmware Update (FFU) functionality, an out-of-bounds write is possible due to missing bounds checking on the PRDT table size. This could lead to local code execution or denial of service without additional execution privileges.

Risk Assessment

A local attacker could exploit this to corrupt memory, crash the system, or execute code. Exploitation requires local access to the affected device.

Recommendation

Apply the vendor firmware update that fixes the missing PRDT size validation. Restrict local access to devices with the vulnerable FFU module.
