In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size which is not guaranteed. A crafted filesystem image may lead to a heap-based buffer overflow resulting in critical data to be corrupted, resulting in the risk of arbitrary code execution by-passing secure boot protections.\n\ud83d\udccf Published: 2025-03-03T14:17:32.517Z\n\ud83d\udccf Modified: 2025-03-03T14:17:32.517Z\n\ud83d\udd17 References:\n1. https://access.redhat.com/security/cve/CVE-2025-0689\n2. https://bugzilla.redhat.com/show_bug.cgi?id=2346122", "creation_timestamp": "2025-03-03T14:29:56.000000Z"}
