{
"lang": "en",
"value": "AV:L - The vulnerability is reached through local filesystem operations (a rename syscall) on a mounted nilfs2 volume built from an attacker-crafted image; there is no network-facing path into nilfs2 directory handling.\nAC:L - The attacker fully controls the on-disk directory inode (i_size = 0 with a garbage first entry and an arbitrary 16-bit rec_len), making the out-of-bounds \"..\\\" pointer and the resulting BUG_ON/OOB write deterministic with no race or memory-layout condition outside attacker control.\nPR:N - The attacker needs no privileges or account on the target — they only supply the malicious nilfs2 image (disk image or removable media); the rename that triggers the bug is an ordinary unprivileged operation on the mounted filesystem.\nUI:R - Because nilfs2 lacks FS_USERNS_MOUNT and requires a block device, the crafted image must be mounted by a privileged user or an automount daemon acting on inserted media before the rename can be performed.\nS:U - The corruption and crash occur within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - nilfs_set_link() dereferences an out-of-bounds nilfs_dir_entry up to ~64 KB past the folio, reading rec_len from adjacent kernel memory, and the resulting heap corruption/prepared-chunk mismatch can be leveraged to disclose kernel memory.\nI:H - When the OOB-read rec_len keeps the BUG_ON check satisfied, `de->inode` and `de->file_type` are written 8+1 bytes at an attacker-chosen offset beyond the folio, giving a controlled out-of-bounds write into adjacent kernel memory that is exploitable for further corruption.\nA:H - The reported and readily reproducible outcome is BUG_ON(to > folio_size(folio)) in __block_write_begin_int(), a kernel oops/panic taken with the folio locked inside an active nilfs transaction, wedging the filesystem or crashing the machine."
