|---|---|---|---|---|---|---|---|
| CVE-2025-0622 | Med | 6.4 | < 2.04-150300.22.52.3 | 2.04-150300.22.52.3 | Feb 18, 2025 | A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vuln | |
| CVE-2024-45783 | Med | 4.4 | < 2.04-150300.22.52.3 | 2.04-150300.22.52.3 | Feb 18, 2025 | A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access. | |
