AZL-57007 CVE-2025-0677 affecting package grub2 for versions less than 2.06-25

A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grubmalloc may be called with a smaller...

CVE-2025-0677

CVE-2025-0677 describes a heap-based out-of-bounds write in GRUB2’s UFS symlink handling. The bug: during a symlink lookup, GRUB2 may allocate a buffer based on inode data size without validating that the symlink data size hasn’t overflowed, causing grub_malloc() to under-allocate. Subsequent dis...
