CVE-2026-45935

Description

A flaw was found in the Linux kernel's NTFS3 filesystem driver. Insufficient bounds checking when processing log records in the DeleteIndexEntryRoot function allows a local attacker to provide a maliciously large entry size. This can lead to a heap buffer overflow, a type of memory corruption, which may result in a denial of service or potentially arbitrary code execution.

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.
