Technical description

In the Linux kernel, the following vulnerability has been resolved:

ext4: add EXT4_IGET_BAD flag to prevent unexpected bad inode

There are many places that will get unhappy (and crash) when ext4_iget()

returns a bad inode. However, if iget the boot loader inode, allows a bad

inode to be returned, because the inode may not be initialized. This

mechanism can be used to bypass some checks and cause panic. To solve this

problem, we add a special iget flag EXT4_IGET_BAD. Only with this flag

we'd be returning bad inode from ext4_iget(), otherwise we always return

the error code if the inode is bad inode.(suggested by Jan Kara)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
