UNISOC Bootloader Out-of-Bounds Write Vulnerability Leading to Local Denial-of-Service

A local denial-of-service vulnerability has been identified in the bootloader of UNISOC chipsets, including SC7731E, SC9832E, SC9863A, T310, T606, T612, T616, T610, T618, T750, T765, T760, T770, T820, and S8000. The issue arises from a missing bounds check, which creates a potential out-of-bounds write condition. This vulnerability does not require any additional execution privileges to exploit.

Impact

Exploitation of this vulnerability can cause a local denial-of-service condition, disrupting normal operation but not allowing for unauthorized access or execution of code.
