CVE-2026-107635 is a medium-severity flaw (CVSS 6.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
