Threats affecting pkg:github/libfvde

CVE-2026-116729 is a heap out-of-bounds read vulnerability in libfvde, a library for FileVault 2 volumes. The flaw occurs in the function libfvde_encrypted_metadata_read_type_0x001a() due to an unbounded strlen call on embedded XML plist data that is not properly NUL-terminated. An attacker can craft a malicious FileVault 2 volume with non-NUL-terminated plist data, causing libfvde_volume_open() to read beyond the allocated heap buffer.

CVE-2026-116728 is a heap out-of-bounds read vulnerability in libfvde, a library for FileVault 2 Core Storage volumes. The flaw occurs because the size of XML plist data is not properly checked against the source metadata block, allowing an attacker to cause a buffer over-read. This can lead to application crashes when processing crafted volumes.
