A maliciouly crafted filesystem may lead some of those buffer size calculation to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result the hfsplus_open_compressed_real() function will write past of the internal buffer length. This flaw may be leveraged to corrupt grub's internal critical data and may result in arbitrary code execution by-passing secure boot protections.\n\ud83d\udccf Published: 2025-03-03T14:16:13.252Z\n\ud83d\udccf Modified: 2025-03-03T14:16:13.252Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/security/cve/CVE-2025-1125\n2. https://bugzilla.redhat.com/show_bug.cgi?id=2346138", "creation_timestamp": "2025-03-03T14:30:01.000000Z"}
