high Nessus Plugin ID 261607

語言:

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，且廠商未提供可用的修補程式。

- LoongArchKVM修正 send_ipi_data() 函式中的堆疊保護器問題 send_ipi_data() 函式中會呼叫 kvm_io_bus_read()參數 *val 的緩衝區大小應至少為 8 位元組。由於部分模擬函式 (如 loongarch_ipi_readl() 和 kvm_eiointc_read()) 會以 8 位元組帶正負號的延伸寫入緩衝區 *val而不管參數 len。否則在啟用 CONFIG_STACKPROTECTOR 時將會有緩衝區溢位問題。錯誤報告如下所示核心錯誤 - 未同步堆疊保護器核心堆疊在以下位置損毀：send_ipi_data+0x194/0x1a0 [kvm] CPU11 UID107 PID2692 通訊
