AlmaLinux 9.2 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.2：CLSA-2026：U 1781347338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：net: mdio: unexport __init-annotated mdio_bus_init() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. modpost used to detect it, but it has been broken for a decade. Recently, I fixed modpost so it started to warn it again, then this showed up in linux-next builds. There are two ways to fix it: - Remove __init - Remove EXPORT_SYMBOL I chose the latter for this case because the only in-tree call-site, drivers/net/phy/phy_device.c is never compiled as modular. (CONFIG_PHYLIB is boolean) (CVE-2022-49350)

  - 已修复 Linux 内核中的下列漏洞：selinux: fix memleak in security_read_state_kernel() In this function, it directly returns the result of __security_read_policy without freeing the allocated memory in *data, cause memory leak issue, so free the memory if
    __security_read_policy failed. [PM: subject line tweak] (CVE-2022-50201)

  - 已修复 Linux 内核中的下列漏洞：usb: typec: tcpci: fix of node refcount leak in tcpci_register_port() I got the following report while doing device(mt6370-tcpc) load test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled: OF: ERROR: memory leak, expected refcount 1 instead of 2, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /i2c/pmic@34/tcpc/connector The 'fwnode' set in tcpci_parse_config() which is called in tcpci_register_port(), its node refcount is increased in device_get_named_child_node(). It needs be put while exiting, so call fwnode_handle_put() in the error path of tcpci_register_port() and in tcpci_unregister_port() to avoid leak. (CVE-2022-50246)

  - 已修复 Linux 内核中的下列漏洞：drivers: serial: jsm: fix some leaks in probe This error path needs to unwind instead of just returning directly. (CVE-2022-50312)

  - 已修复 Linux 内核中的下列漏洞：thermal: intel_powerclamp: Use get_cpu() instead of smp_processor_id() to avoid crash When CPU 0 is offline and intel_powerclamp is used to inject idle, it generates kernel BUG: BUG: using smp_processor_id() in preemptible [00000000] code:
    bash/15687 caller is debug_smp_processor_id+0x17/0x20 CPU: 4 PID: 15687 Comm: bash Not tainted 5.19.0-rc7+ #57 Call Trace: <TASK> dump_stack_lvl+0x49/0x63 dump_stack+0x10/0x16 check_preemption_disabled+0xdd/0xe0 debug_smp_processor_id+0x17/0x20 powerclamp_set_cur_state+0x7f/0xf9 [intel_powerclamp] ... ... Here CPU 0 is the control CPU by default and changed to the current CPU, if CPU 0 offlined. This check has to be performed under cpus_read_lock(), hence the above warning. Use get_cpu() instead of smp_processor_id() to avoid this BUG. [ rjw: Subject edits ] (CVE-2022-50494)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 Linux 内核中，已解决以下漏洞： vhost-vdpa: fix use after free in vhost_vdpa_probe() The put_device() calls vhost_vdpa_release_dev() which calls ida_simple_remove() and frees v. So this call to ida_simple_remove() is a use after free and a double free. (CVE-2023-52795)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
