CVE-2026-40026 Details
Description
The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the ISO9660 filesystem parser where the parse_susp() function trusts len_id, len_des, and len_src fields from the disk image to memcpy data into a stack buffer without verifying that the source data falls within the parsed SUSP block. An attacker can craft a malicious ISO image that causes reads past the end of the SUSP data buffer, and a zero-length SUSP entry can trigger an infinite parsing loop.
A out-of-bounds read vulnerability has been identified in The Sleuth Kit versions through 4.14.0, within the ISO9660 filesystem parser. The issue arises in the parse_susp() function, which improperly trusts the len_id, len_des, and len_src fields from the disk image. This lack of validation allows data to be copied into a stack buffer using memcpy, potentially leading to reads beyond the intended SUSP data buffer. Additionally, a zero-length SUSP entry can cause an infinite parsing loop.
Users can update to The Sleuth Kit version 4.14.0 or later, where this vulnerability has been fixed.
