概要
CentOS Linux 主機缺少一個或多個安全性更新。說明
CentOS Linux 8 主機已安裝的套件會受到 TuxCare CENTOS-STREAM8：CLSA-2024：1729874131 公告中提及的多個弱點影響。- 已解決 Linux 核心中的下列弱點：mm, slub: fix potential memoryleak in kmem_cache_open() In error path, the random_seq of slub cache might be leaked. Fix this by using
__kmem_cache_release() to release all the relevant resources. (CVE-2021-47466)
- 在 5.18.17 版之前的 Linux 核心中，發現 x86 KVM 子系統存在問題。無權限的來賓使用者可入侵來賓核心，這是因為在某些 KVM_VCPU_PREEMPTED 情況下，程式未正確處理 TLB 排清作業。(CVE-2022-39189)
- Linux 核心中有一個釋放後使用弱點，可遭惡意利用來提升本機權限。必須設定核心組態旗標 CONFIG_TLS 或 CONFIG_XFRM_ESPINTCP，才能達到弱點，但該作業不需要任何權限。struct inet_connection_sock 的 icsk_ulp_data 有一個釋放後使用錯誤。啟用 CONFIG_TLS 時，使用者可在已連線的 tcp 通訊端上安裝 tls 內容 (struct tls_context)。如果此通訊端中斷連線並重新用作接聽程式，則不會清除內容。如果從接聽程式建立新的通訊端，則內容會繼承並受到影響。setsockopt TCP_ULP 作業不需要任何權限。建議升級過去的提交 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)
- 已解決 Linux 核心中的下列弱點：drm/amdgpu: Fix a null pointer access when the smc_rreg pointer is NULL In certain types of chips, such as VEGA20, reading the amdgpu_regs_smc file could result in an abnormal null pointer access when the smc_rreg pointer is NULL. Below are the steps to reproduce this issue and the corresponding exception log: 1. Navigate to the directory:
/sys/kernel/debug/dri/0 2. Execute command: cat amdgpu_regs_smc 3. Exception Log:: [4005007.702554] BUG:
