{"id":"DEBIAN-CVE-2024-53690","details":"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.
