CVE-2023-53328 - fs/ntfs3: Enhance sanity check while generating attr_list
CVE ID : CVE-2023-53328
Published : Sept. 16, 2025, 5:15 p.m. | 1 hour, 21 minutes ago
Description : In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Enhance sanity check while generating attr_list ni_create_attr_list uses WARN_ON to catch error cases while generating attribute list, which only prints out stack trace and may not be enough. This repalces them with more proper error handling flow.
