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： can: m_can:
    m_can_{read_fifo,echo_tx_event}(): shift timestamp to full 32 bits In commit 1be37d3b0414 (can: m_can:
    fix periph RX path: use rx-offload to ensure skbs are sent from softirq context) the RX path for peripheral devices was switched to RX-offload. Received CAN frames are pushed to RX-offload together with a timestamp. RX-offload is designed to handle overflows of the timestamp correctly, if 32 bit timestamps are provided. The timestamps of m_can core are only 16 bits wide. So this patch shifts them to full 32 bit before passing them to RX-offload. (CVE-2022-49659)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
