CVE-2026-40025
Description
A flaw was found in The Sleuth Kit. An attacker can exploit this vulnerability by crafting a malicious Apple File System (APFS) disk image. This flaw allows for an out-of-bounds read in the APFS filesystem keybag parser, specifically within the wrapped_key_parser class, due to a lack of bounds checking on attacker-controlled length fields. This can lead to information disclosure or a denial of service (DoS) by crashing the system when any Sleuth Kit tool processes the malicious image.
Statement
Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
