CVE-2026-107635

Dislocker through 0.7.3 Out-of-Bounds Heap Read via VMK/FVEK Datum Size Underflow

Dislocker through 0.7.3 contains an integer underflow vulnerability in get_vmk() and get_fvek() that allows attackers to trigger out-of-bounds heap reads via crafted datum sizes. Attackers can supply a malicious BitLocker volume image with a datum_size smaller than the 36-byte AES-CCM header, causing hexdump() to over-read and crash dislocker.

CVE-2026-107634

Dislocker through 0.7.3 Heap Out-of-Bounds Read via BitLocker Metadata Dataset Size

Dislocker through 0.7.3 contains a heap out-of-bounds read vulnerability in get_dataset() and get_next_datum() that never validate dataset and datum sizes against the metadata allocation. Attackers can craft a BitLocker volume image with inflated dataset or datum sizes that, when opened or mounted, crashes dislocker or discloses adjacent heap memory.
