CVE-2026-53029

Description

A flaw was found in the Linux kernel's ntfs3 filesystem driver. This vulnerability occurs due to an uninitialized local variable (lcn) when handling zero-length data during I/O operations. An attacker could potentially exploit this flaw to cause a denial of service or information disclosure due to unpredictable behavior resulting from the use of uninitialized memory.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Memory

If the uninitialized pointer is used in a read operation, an attacker might be able to read sensitive portions of memory.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

If the uninitialized pointer references a memory location that is not accessible to the product, or points to a location that is "malformed" (such as NULL) or larger than expected by a read or write operation, then a crash may occur.

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

If the uninitialized pointer is used in a function call, or points to unexpected data in a write operation, then code execution may be possible.
