CVE-2024-45782

CVE-2024-45782 affects grub2, specifically the HFS filesystem path where grub_fs_mount() uses strcpy on a user-provided volume name, enabling a heap-based out-of-bounds write and potential secure-boot bypass. Affected packages include grub2 prior to the updated 2.06 releases; remediation is to up...

AZL-57551 CVE-2025-0689 affecting package grub2 for versions less than 2.06-15

When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its internal buffers. In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size whi...
