请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

CentOS Linux 8 主机上存在安装的程序包，该程序包受到 TuxCare CENTOS-STREAM8：CLSA-2026：1791780738公告中提及的多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：mm/khugepaged: invoke MMU notifiers in shmem/file collapse paths Any codepath that zaps page table entries must invoke MMU notifiers to ensure that secondary MMUs (like KVM) don't keep accessing pages which aren't mapped anymore. Secondary MMUs don't hold their own references to pages that are mirrored over, so failing to notify them can lead to page use-after-free. I'm marking this as addressing an issue introduced in commit f3f0e1d2150b (khugepaged: add support of collapse for tmpfs/shmem pages), but most of the security impact of this only came in commit 27e1f8273113 (khugepaged: enable collapse pmd for pte-mapped THP), which actually omitted flushes for the removal of present PTEs, not just for the removal of empty page tables.

  - 已修复 Linux 内核中的下列漏洞：virtio_net: fix xdp_rxq_info bug after suspend/resume The following sequence currently causes a driver bug warning when using virtio_net: # ip link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac
    __dev_close_many+0xac/0x140 __dev_change_flags+0xd8/0x210 dev_change_flags+0x24/0x64 do_setlink+0x230/0xdd0 ... This happens because virtnet_freeze() frees the receive_queue completely (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down() and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if netif_running(). However, this should not make any functional difference since the refill work should only be active if the network interface is actually up. (CVE-2022-49687)

  - 已修复 Linux 内核中的下列漏洞：bpf, sockmap: Fix repeated calls to sock_put() when msg has more_data In tcp_bpf_send_verdict() redirection, the eval variable is assigned to
    __SK_REDIRECT after the apply_bytes data is sent, if msg has more_data, sock_put() will be called multiple times. We should reset the eval variable to __SK_NONE every time more_data starts. This causes: IPv4:

  - 已修复 Linux 内核中的下列漏洞：crypto: scomp - fix req->dst buffer overflow The req->dst buffer size should be checked before copying from the scomp_scratch->dst to avoid req->dst buffer overflow problem. (CVE-2023-52612)

  - 已修复 Linux 内核中的下列漏洞：net: atlantic: eliminate double free in error handling logic Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.
    (CVE-2023-52664)
