CVE-2026-23474

Description

A flaw was found in the Linux kernel's Memory Technology Device (mtd) subsystem, specifically within the RedBoot partition table parser. A local user could trigger a buffer overflow when the system attempts to read beyond the allocated buffer size during partition table parsing. This vulnerability can lead to a system boot crash, resulting in a Denial of Service (DoS).

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.
