UBUNTU-CVE-2024-47740: Medium severity ubuntu/linux-aws vulnerability

Published Oct 21, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: f2fs: Require FMODEWRITE for atomic write ioctls The F2FS ioctls for starting and committing atomic writes check for inodeownerorcapable(), but this does not give LSMs like SELinux or Landlock an opportunity to deny the write access - if the caller's FSUID matches the inode's UID, inodeownerorcapable() immediately returns true. There are scenarios where LSMs want to deny a process the ability to write particular files, even files that the FSUID of the process owns; but this can currently partially be bypassed using atomic write ioctls in two ways: - F2FSIOCSTARTATOMICREPLACE + F2FSIOCCOMMITATOMICWRITE can truncate an inode to size 0 - F2FSIOCSTARTATOMICWRITE + F2FSIOCABORTATOMICWRITE can revert changes another process concurrently made to a file Fix it by requiring FMODEWRITE for these operations, just like for F2FSIOCMOVERANGE. Since any legitimate caller should only be using these ioctls when intending to write into the file, that seems unlikely to break anything.

  90. Compensating control

    Require FMODE_WRITE for F2FS_IOC_START_ATOMIC_REPLACE, F2FS_IOC_COMMIT_ATOMIC_WRITE, F2FS_IOC_START_ATOMIC_WRITE, and F2FS_IOC_ABORT_ATOMIC_WRITE, as is done for F2FS_IOC_MOVE_RANGE, so LSMs can deny unauthorized write access.

Frequently Asked Questions

1

What access would an attacker need to exploit this issue?

The attacker needs local access to an F2FS file and must satisfy the inode ownership-or-capability check, such as having an FSUID matching the file owner. The relevant scenario is where an LSM policy such as SELinux or Landlock would otherwise deny write access.

2

What could exploitation allow despite an LSM write restriction?

Atomic-write ioctls can be used to truncate an inode to zero bytes using START_ATOMIC_REPLACE and COMMIT_ATOMIC_WRITE. START_ATOMIC_WRITE followed by ABORT_ATOMIC_WRITE can also revert changes made concurrently by another process.

3

Which Ubuntu kernel package families are listed as affected?

The listed software includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, and their FIPS variants: ubuntu/linux-fips, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.
