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。

  - 已修复 Linux 内核中的下列漏洞：mtd: require write permissions for locking and badblock ioctls MEMLOCK, MEMUNLOCK and OTPLOCK modify protection bits. Thus require write permission. Depending on the hardware MEMLOCK might even be write-once, e.g. for SPI-NOR flashes with their WP# tied to GND. OTPLOCK is always write-once. MEMSETBADBLOCK modifies the bad block table.
    (CVE-2021-47055)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: mtd: require write permissions for     locking and badblock ioctls MEMLOCK, MEMUNLOCK and OTPLOCK modify protection bits. Thus require write     permission. Depending on the hardware MEMLOCK might even be write-once, e.g. for SPI-NOR flashes with     their WP# tied to GND. OTPLOCK is always write-once. MEMSETBADBLOCK modifies the bad block table.
    (CVE-2021-47055)

Note that Nessus relies on the presence of the package as reported by the vendor.
