Out-of-bounds write in grub - CVE-2022-28737

Vulnerability identifier: #VU64067

CSH Severity: Low

CVSS v4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-28737

CWE-ID: CWE-787

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to a boundary error in the handle_image() function when shim tries to load and execute crafted EFI executables. A local privileged user can trigger an out-of-bounds write error and bypass secure boot protection mechanism.
