Linux · Linux Kernel · CVE-2023-0122
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions v6.0-rc1 through v6.0-rc3
**Description**
A NULL pointer dereference vulnerability in the Linux kernel NVMe functionality, in the `nvmet setup auth()` function, allows an attacker to perform a Pre-Auth Denial of Service (DoS) attack on a remote machine.
**Recommendations**
For Linux kernel versions v6.0-rc1 through v6.0-rc3, update to version v6.0-rc4 or later to resolve the issue. As a temporary workaround, consider disabling the `nvmet setup auth()` function until a patch is available. Restrict access to the NVMe functionality to minimize the risk of exploitation.
