UBUNTU-CVE-2025-38615: High severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: cancle set bad inode after removing name fails The reproducer uses a file0 on a ntfs3 file system with a corrupted ilink. When renaming, the file0's inode is marked as a bad inode because the file name cannot be deleted. The underlying bug is that makebadinode() is called on a live inode. In some cases it's "icache lookup finds a normal inode, dsplicealias() is called to attach it to dentry, while another thread decides to call makebadinode() on it - that would evict it from icache, but we'd already found it there earlier". In some it's outright "we have an inode attached to dentry - that's how we got it in the first place; let's call makebadinode() on it just for shits and giggles".

Event History
Frequently Asked Questions
Which Ubuntu kernel packages are listed for this issue?
The listed packages are ubuntu/linux-azure-fde, ubuntu/linux-realtime, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-gke, ubuntu/linux-gkeop, ubuntu/linux-riscv, and ubuntu/linux-aws-fips.
What condition is involved in triggering the faulty inode handling?
The reported reproducer uses an NTFS3 filesystem containing a file with a corrupted i_link. Renaming that file can fail to remove its name and result in make_bad_inode() being called on a live inode.
What does the severity vector indicate about exploit prerequisites and impact?
The vector rates the issue as network-accessible with low attack complexity and no required privileges, but with user interaction required. It indicates no confidentiality impact and high integrity and availability impact.
