Vulnerability from github – Published: 2025-12-24 15:30 – Updated: 2026-08-04 12:34In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Return error for inconsistent extended attributes
ntfs_read_ea is called when we want to read extended attributes. There are some sanity checks for the validity of the EAs. However, it fails to return a proper error code for the inconsistent attributes, which might lead to unpredicted memory accesses after return.
