概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點,供應商表示將不會修補。
說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件,且供應商未提供可用的修補程式。
- 在 Linux 核心中,已解決下列弱點: 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)
請注意,Nessus 依賴供應商報告的套件存在。
