Description

erofs: fix file-backed mounts over FUSE

In the Linux kernel, the following vulnerability has been resolved:

erofs: fix file-backed mounts over FUSE

syzbot reported a null-ptr-deref in fuse_read_args_fill:

fuse_read_folio+0xb0/0x100 fs/fuse/file.c:905

filemap_read_folio+0xc6/0x2a0 mm/filemap.c:2367

do_read_cache_folio+0x263/0x5c0 mm/filemap.c:3825

read_mapping_folio include/linux/pagemap.h:1011 [inline]

erofs_bread+0x34d/0x7e0 fs/erofs/data.c:41

erofs_read_superblock fs/erofs/super.c:281 [inline]

erofs_fc_fill_super+0x2b9/0x2500 fs/erofs/super.c:625

Unlike most filesystems, some network filesystems and FUSE need

unavoidable valid file pointers for their read I/Os [1].

Anyway, those use cases need to be supported too.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: None.
  • Availability impact: High — total loss, or loss the attacker controls.
