Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.12.6 and classified as problematic. Affected by this vulnerability is the function nilfs_iget of the file fs/inode.c. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: nilfs2: prevent use of deleted inode syzbot reported a WARNING in nilfs_rmdir. [1] Because the inode bitmap is corrupted, an inode with an inode number that should exist as a ".nilfs" file was reassigned by nilfs_mkdir for "file0", causing an inode duplication during execution. And this causes an underflow of i_nlink in rmdir operations. The inode is used twice by the same task to unmount and remove directories ".nilfs" and "file0", it trigger warning in nilfs_rmdir. Avoid to this issue, check i_nlink in nilfs_iget(), if it is 0, it means that this inode has been deleted, and iput is executed to reclaim it.
