Description

wifi: wilc1000: unregister wiphy only if it has been registered

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

wifi: wilc1000: unregister wiphy only if it has been registered

There is a specific error path in probe functions in wilc drivers (both

sdio and spi) which can lead to kernel panic, as this one for example

when using SPI:

Unable to handle kernel paging request at virtual address 9f000000 when read

[9f000000] *pgd=00000000

Internal error: Oops: 5 [#1] ARM

The issue can easily be reproduced, for example by not wiring correctly

a wilc device through SPI (and so, make it unresponsive to early SPI

commands). It is due to a recent change decoupling wiphy allocation from

wiphy registration, however wilc_netdev_cleanup has not been updated

accordingly, letting it possibly call wiphy unregister on a wiphy which

has never been registered.

Fix this crash by moving wiphy_unregister/wiphy_free out of

wilc_netdev_cleanup, and by adjusting error paths in both drivers

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.
