Detailsinfo

A vulnerability was found in Aorimn Dislocker up to 0.7.3. It has been classified as problematic. Affected is the function get_vmk/get_fvek of the component Datum Handler. The manipulation of the argument datum_size with an unknown input leads to a integer underflow vulnerability. CWE is classifying the issue as CWE-191. The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-107635 since 10/08/2026. The exploitability is told to be easy. Local access is required to approach this attack.
