Local code execution via excess function input
Published Sep 12, 2022 · Updated Sep 16, 2024
Stack-based buffer overflow in Dell Client Platform BIOS on pre-21Q4 platforms allows local users to execute arbitrary code. Dell identifies an unspecified BIOS function that receives excess data but does not disclose the operation that overruns the stack buffer. A local authenticated account is required, and successful exploitation runs attacker-controlled code on the affected system.
