Description

mac802154: Fix potential RCU dereference issue in mac802154_scan_worker

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

mac802154: Fix potential RCU dereference issue in mac802154_scan_worker

In the mac802154_scan_worker function, the scan_req->type field was

accessed after the RCU read-side critical section was unlocked. According

to RCU usage rules, this is illegal and can lead to unpredictable

behavior, such as 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 scan_req->type value is now stored in a local

variable scan_req_type while still within the RCU read-side critical

section. The scan_req_type is then used after the RCU lock is released,

ensuring that the type value is safely accessed without violating RCU

rules.

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 high, integrity high, availability high.
