Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw related to handling of inodes. Specifically, the issue arises when obtaining the boot loader inode, potentially allowing a bad inode to be returned, bypassing certain checks and leading to a system panic. A flag, EXT4 IGET BAD, was added to prevent returning bad inodes from the ext4 iget() function, except when this flag is present. This resolves the issue by ensuring proper error handling when dealing with potentially uninitialized inodes.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
