1 CVE-2020-25647 787 Exec Code Mem. Corr. Bypass 2021-03-03 2021-05-01
7.2
None Local Low Not required Complete Complete Complete
A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
2 CVE-2020-25632 416 Exec Code Bypass 2021-03-03 2021-05-01
7.2
None Local Low Not required Complete Complete Complete
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
