CentOS Linux 8.5 主機已安裝的套件會受到 TuxCare CENTOS8.5：CLSA-2025：1747688831 公告中提及的多個弱點影響。

  - 在 Linux 核心的 eBPF 中發現超出邊界 (OOB) 記憶體存取瑕疵，這是不當輸入驗證所致。具有特殊特權的本機攻擊者可利用此瑕疵造成系統當機或洩漏核心資訊。(CVE-2021-4204)

  - 已解決 Linux 核心中的下列弱點：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)

  - 已解決 Linux 核心中的下列弱點：cifs: fix potential double free during failed mount RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=2088799 (CVE-2022-49541)

  - 已解決 Linux 核心中的下列弱點：block: Fix handling of offline queues in blk_mq_alloc_request_hctx() This patch prevents that test nvme/004 triggers the following: UBSAN:
