CVE-2024-45781 is a heap-based out-of-bounds write vulnerability in GRUB2's UFS filesystem module. When GRUB2 reads a symbolic link name from a UFS filesystem, it does not validate the supplied string length before use. A maliciously constructed UFS filesystem or symlink entry can therefore cause a heap out-of-bounds write.
