Description

s390/dasd: fix error recovery leading to data corruption on ESE devices

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

s390/dasd: fix error recovery leading to data corruption on ESE devices

Extent Space Efficient (ESE) or thin provisioned volumes need to be

formatted on demand during usual IO processing.

The dasd_ese_needs_format function checks for error codes that signal

the non existence of a proper track format.

The check for incorrect length is to imprecise since other error cases

leading to transport of insufficient data also have this flag set.

This might lead to data corruption in certain error cases for example

during a storage server warmstart.

Fix by removing the check for incorrect length and replacing by

explicitly checking for invalid track format in transport mode.

Also remove the check for file protected since this is not a valid

ESE handling case.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is high, 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 high, integrity high, availability high.

CVSS metrics in full

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

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • 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: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
