Amazon Linux 2023bpftool6.12、kernel6.12、kernel6.12-devel (ALAS2023-2026-1489)

high Nessus Plugin ID 304278

概要

遠端 Amazon Linux 2023 主機缺少一個安全性更新。

說明

因此,會受到 ALAS2023-2026-1489 公告中所提及的多個弱點影響。

在 Linux 核心中,下列弱點已解決:

mm/hugetlb修正 hugetlb_pmd_shared() (CVE-2026-23100)

在 Linux 核心中,下列弱點已解決:bus: fsl-mc: fix use-after-free in driver_override_show() The driver_override_show() function reads the driver_override string without holding the device_lock. However, driver_override_store() uses driver_set_override(), which modifies and frees the string while holding the device_lock. This can result in a concurrent use-after-free if the string is freed by the store function while being read by the show function. Fix this by holding the device_lock around the read operation. (CVE-2026-23221)

Tenable 已直接從所測試產品的安全公告擷取前置描述區塊。

請注意,Nessus 並未測試這些問題,而是僅依據應用程式自我報告的版本號碼作出判斷。

解決方案

執行「dnf update kernel6.12 --releasever 2023.10.20260325」或 或「dnf update --advisory ALAS2023-2026-1489 --releasever 2023.10.20260325」以更新系統。
