Linux Kernel ntfs_set_ea HasEA Flag Update on Setxattr Failure
CVE-2026-98133 Published on September 25, 2026
ntfs: leave HasEA flag untouched on setxattr failure
In the Linux kernel, the following vulnerability has been resolved:
ntfs: leave HasEA flag untouched on setxattr failure
In ntfs_set_ea(), the exit path unconditionally updates the HasEA
flag based on ea_info_qsize. When an error occurs before
ea_info_qsize is updated, NInoClearHasEA() hides existing on-disk
EAs until the inode is evicted.
Only update the flag on success.
