Linux · Linux Kernel · CVE-2021-47165
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to a shutdown crash in the Linux kernel when the main component is not probed, for example, when the dw-hdmi module is not loaded yet or in probe defer. This results in a kernel NULL pointer dereference at a virtual address. The call trace includes functions such as `meson drv shutdown()`, `platform drv shutdown()`, `device shutdown()`, `kernel restart prepare()`, `kernel restart()`, and ` arm64 sys reboot()`. To resolve this, it is recommended to check if the `priv` struct has been allocated before using it.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
