CVE-2025-71311
Description
A flaw was found in the Linux kernel's fs/ntfs3 component. When new memory pages (folios) are allocated for the NTFS3 file system without being properly initialized, and a read operation is skipped, parts of these folios may contain uninitialized memory. This can lead to a memory corruption vulnerability.
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.
