MEDIUMCVSS 5.5/10

Last modified

CVE-2026-107635 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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..
