如 TuxCare CENTOS8.5：CLSA-2025：1747688831公告所述，CentOS Linux 8.5 主机上安装的程序包受到多个漏洞的影响。

  - 在 Linux 内核的 eBPF 中发现越界 (OOB) 内存访问缺陷，这是不当输入验证所致。具有特权的本地攻击者可利用此缺陷造成系统崩溃或泄露内部信息。(CVE-2021-4204)

  - 已修复 Linux 内核中的下列漏洞：ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface() There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and the number of it's interfaces less than 4, an out-of-bounds read bug occurs when parsing the interface descriptor for this device. Fix this by checking the number of interfaces. (CVE-2022-48701)

  - 已修复 Linux 内核中的下列漏洞：cifs: fix potential double free during failed mount RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=2088799 (CVE-2022-49541)

  - 已修复 Linux 内核中的下列漏洞：block: Fix handling of offline queues in blk_mq_alloc_request_hctx() This patch prevents that test nvme/004 triggers the following: UBSAN:
