Description

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.

Affected products

Linux kernel: from 7.1 before 7.2.7; 7.3-rc1 — fixed in 7.2.7

How to fix

Upgrade to a fixed version: Linux kernel 7.2.7. Check the vendor advisory for mitigations.
