Description

wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param

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

wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param

In the wilc_parse_join_bss_param function, the TSF field of the ies

structure is accessed after the RCU read-side critical section is

unlocked. According to RCU usage rules, this is illegal. Reusing this

pointer can lead to unpredictable behavior, including accessing memory

that has been updated or causing use-after-free issues.

This possible bug was identified using a static analysis tool developed

by myself, specifically designed to detect RCU-related issues.

To address this, the TSF value is now stored in a local variable

ies_tsf before the RCU lock is released. The param->tsf_lo field is

then assigned using this local variable, ensuring that the TSF value is

safely accessed.

How this vulnerability can be exploited

This issue can be reached from an adjacent network, attack complexity is low, an attacker needs no 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 low, availability high.

CVSS metrics in full

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

  • Attack vector: Adjacent network — the attacker has to sit on the same local or logical network.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: None — an unauthenticated stranger can try it.
  • 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: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: High — total loss, or loss the attacker controls.
