CVE-2026-99260

Description

A flaw was found in the Linux kernel's NTFS file system implementation. This vulnerability allows a local user to cause a Denial of Service (DoS) or file system corruption when setting compression or sparse attributes on a file. Because the driver fails to properly convert resident data stored directly within the file record into non-resident storage, the file system is left in an invalid state.

Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart

If a memory buffer is accessed using an incompatible type, and the allocated buffer is smaller than the type that the code is attempting to access, then an attacker could read or write memory outside the bounds of the buffer, leading to a crash or possibly code execution.
