CVE-2024-45776: Red Hat Enterprise Linux 10

Medium severity, CVSS 6.7. EPSS: 0.3% chance of exploitation in the next 30 days.

When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections.
