Details

In Das U-Boot through 2020.01, a double free has been found in the cmd/gpt.c dorenamegpt_parts() function. Double freeing may result in a write-what-where condition, allowing an attacker to execute arbitrary code. NOTE: this vulnerablity was introduced when attempting to fix a memory leak identified by static analysis.
