简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞,但供应商表示不会修补此漏洞。
描述
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: mlxsw: spectrum: Guard against invalid local ports When processing events generated by the device's firmware, the driver protects itself from events reported for non-existent local ports, but not for the CPU port (local port 0), which exists, but does not have all the fields as any local port. This can result in a NULL pointer dereference when trying access 'struct mlxsw_sp_port' fields which are not initialized for CPU port. Commit 63b08b1f6834 (mlxsw:
spectrum: Protect driver from buggy firmware) already handled such issue by bailing early when processing a PUDE event reported for the CPU port. Generalize the approach by moving the check to a common function and making use of it in all relevant places. (CVE-2022-49134)
请注意,Nessus 依赖供应商报告的程序包是否存在进行判断。
