CVE-2022-28736

Name of the Vulnerable Software and Affected Versions GRUB2 (affected versions not specified)

Description The issue is related to a use-after-free vulnerability in the grub cmd chainloader() function. This function is used to boot operating systems that do not support multiboot and do not have direct support from GRUB2. When the chainloader command is executed more than once, the vulnerability is triggered. If an attacker can control GRUB2's memory allocation pattern, sensitive data may be exposed, and arbitrary code execution can be achieved.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
