Linux Distros 未修補的弱點：CVE-2025-21979

high Nessus Plugin ID 246542

語言:

概要

Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。

說明

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

- 已解決 Linux 核心中的下列弱點：wifi: cfg80211: cancel wiphy_work before freeing wiphy A wiphy_work can be queued from the moment the wiphy is allocated and initialized (i.e. wiphy_new_nm). When a wiphy_work is queued, the rdev::wiphy_work is getting queued. If wiphy_free is called before the rdev::wiphy_work had a chance to run, the wiphy memory will be freed, and then when it eventally gets to run it'll use invalid memory. Fix this by canceling the work before freeing the wiphy.
(CVE-2025-21979)

請注意，Nessus 依賴供應商報告的套件存在。

解決方案

目前尚未有已知的解決方案。
