AI-suggested

A fix has been implemented in the Linux kernel as indicated by the presence of fixed commit versions. Users should update their Linux kernel to a version including these fixes to avoid the issue. No additional mitigation actions are required.

Description

A vulnerability in the Linux kernel's Integrity Measurement Architecture (IMA) was addressed by returning an error early when file extended attributes (xattr) cannot be changed. During early boot, the filesystem is read-only, and attempts to change xattrs on ext4 filesystems fail due to ext4 transactions starting improperly. This fix prevents warnings and potential issues by detecting the file state early and returning an error without proceeding with the transaction.
