GHSA-PM8P-867F-R9W3

Vulnerability from github – Published: 2022-05-24 22:28 – Updated: 2022-05-24 22:28

Details

When booting a Zync-7000 SOC device from nand flash memory, the nand driver in the ROM does not validate the inputs when reading in any parameters in the nand’s parameter page. IF a field read in from the parameter page is too large, this causes a buffer overflow that could lead to arbitrary code execution. Physical access and modification to the Zynq-7000 device is needed to replace the original nand flash memory with a nand flash emulator for this attack to be successful.

CVE-2021-27208 (GCVE-0-2021-27208)

Vulnerability from cvelistv5 – Published: 2021-03-15 12:27 – Updated: 2024-08-03 20:40

Summary

When booting a Zync-7000 SOC device from nand flash memory, the nand driver in the ROM does not validate the inputs when reading in any parameters in the nand’s parameter page. IF a field read in from the parameter page is too large, this causes a buffer overflow that could lead to arbitrary code execution. Physical access and modification of the board assembly on which the Zynq-7000 SoC device mounted is needed to replace the original NAND flash memory with a NAND flash emulation device for this attack to be successful.
